ALMA telescope finds 15 extremely dark galaxies unidentified until now!!!






      With the help of ALMA (Atacama Large Millimeter/submillimeter Array), scientists have observed the "Subaru/XMM-Newton Deep Survey Field" in the direction of the constellation Cetus, and succeeded in identifying 15 extremely dark galaxies which had been previously unknown.

 In addition, they also successfully measured the number density of galaxies with 10 times less luminosity than ones previously observed with the conventional millimeter instruments.

 Based on the observations with ALMA telescope, the research team led by Bunyo Hatsukade, a postdoc researcher, and Kouji Ohta, a professor, both from the Graduate School of Science, Kyoto University, have revealed that approximately 80 percent of the unidentifiable millimeter wave signals from the universe are actually emitted from galaxies.

 Their densities well match the prediction by theories of galaxy formation. Therefore, the researchers consider that they managed to capture more like "normal" galaxies, which had been impossible to detect up to now, than extremely bright "submillimeter-luminous galaxies".

 Using ALMA and the Subaru Telescope , the research team is now seeking to uncover the overall picture of galaxy formation and evolution while conducting observations of much darker galaxies.

 Conventional research on distant galaxies has been carried out mainly with visible light and near infrared light. However, it is possible that many galaxies in the universe have been overlooked as much of that radiation is largely absorbed by cosmic dust. That is why millimeter and submillimeter wave observations are important.

ALMA telescope finds 15 extremely dark galaxies unidentified until now
 Stellar light absorbed by dust is reradiated from the dust as millimeter/submillimeter waves. Therefore galaxies, even those that it has not been possible to observe with optical telescopes, can be detected using these wavebands. Furthermore, millimeter/submillimeter waves are suitable for observation of distant galaxies. This is because the more distant the galaxy is, the more luminous part of light we can see due to the shift of wavelength of light by the expansion of the universe.

 This effect is called "negative K correction" and it compensates the source dimming in the distant universe.

 In past observations, gigantic galaxies deeply covered in dust, where several hundreds to thousands of stars are actively forming per year, have been detected with millimeter/submillimeter waves. To capture the overall picture of galaxies in the universe, it is important to observe "general galaxies" which have moderate star-formation activities. However, it has not been possible to detect faint galaxies due to the low sensitivity of existing observation instruments.

 The research team observed a field named "Subaru/XMM-Newtown Deep Survey Field," located in the direction of the constellation Cetus, with the ALMA telescope. As a result, they succeeded in finding 15 extremely dark galaxies that were unidentified until now.

 "It is thanks to the high performance of ALMA, which is proudly said to be the best in the world, that observations like this have been made possible," said Hatsukade.

 With the ALMA observations the team successfully measured the number density of galaxies approximately 10 times darker than the millimeter wave research results up to now.

 The new results agree well with the prediction by the theories of galaxy formation. That means, the galaxies detected in this research are the faint but dust-rich galaxies and they are most likely to be similar in type to normal galaxies not detected before.

 In regards to this, Professor Ohta commented, "This is a big step towards getting the big picture of galaxy evolution as the objects connecting especially bright galaxies in millimeter/submillimeter waves and normal galaxies were detected with ALMA."

 Furthermore, the team concluded that approximately 80 percent of the sources of the cosmic background radiation within the millimeter/submillimeter wavebands are more "normal galaxies" like those detected by ALMA this time. 



Georgia Institute of Technology Develops Superhydrophobic Paper For Inexpensive Diagnostic Use




Superhydrophobic Paper



Taking inspiration from the water repelling qualities of lotus leaves researchers Lester Li, Victor Breedveld and Dennis Hess of Georgia Institute of Technology have come up with a superhydrophobic paper that has been proven to repel most liquids and oils. The paper is made from standard softwood and hardwood fibers. The fibers then undergo the standard manufacturing process where the cellulose in them in broken down into smaller parts by mechanical grinding. In the conventional way the paper is pressed in presence of water, but while making this paper the water is removed and butanol is added instead. Butanol inhibits the hydrogen bonding that normally takes place between cellulose allowing better control of their spacing.
 

 In the next step, the researchers used an oxygen plasma etching process to remove the layer of ‘fluffy’ cellulose layer to expose the ‘rougher’ layer of crystalline cellulose nanofibrils on which a thin coating of a fluoropolymer is applied to give it the liquid repelling capability. During the testing process the paper was able to repel water, motor oil, ethylene glycol and n-hexadecane solvent. Researchers have also managed to print patterns on the paper using a hydrophobic ink and a desktop printer. The liquid droplets adhered to the ink pattern and were repelled by the rest of the paper. The team hopes to see that their invention could lead to the development of inexpensive biomedical diagnostic tests where a droplet of liquid containing antigens can be rolled on to printed surface where it would be in contact with diagnostic chemicals and depending upon the reagents they would help identify the disease.



 You might have already read about the Superomniphobic Layer developed by the University of Michigan but the difference between both is flexibility. The paper version is very flexible and to some extent cheaper than its predecessor.

Curiosity Rover Bumps Into Pebbles On Mars, Landscape Might Have Been Shaped By Water



 Marsrocks


With NASA trying really hard from quite a few years to find water on the surface of Mars, they have been collecting real good proof over the years. To add another evidence to the lot, Curiosity, the Rover sent by NASA on Mars, came across pebbles near the Gale Crater. Pebbles are usually formed when they are eroded by wind or water, and these pebbles seemed pretty close to the ones formed due to water, the same way as on Earth. Pebbles roll and bump onto other pebbles and settle at places, eventually forming their well rounded edges. Wind couldn't be the reason behind them since these pebbles seemed too big, about 1.5 inches in diameter. These kind of pebbles have not only been found near the Gale Crater but also on other parts of the Red Planet.


 Many rock formations and landscapes on Mars have been found to look similar to the ones carved out of rivers and streams on our planet, still adding to the possibility that water once flowed over the barren planet. The parts where these pebbles were found are reported to have had ankle deep water and sometimes have been waist deep. The pebbles have also been analysed and found to have not travelled a distance more than nine miles.
 

 Mars has always been in the news frequently, with Curiosity finding something interesting almost every month. This planet is supposed to be the closest to the conditions seen on Earth, but with time Mars might have died away. The people at NASA are determined to find water on the dusty planet and are really hoping in to bump into extra-terrestrial life up there soon. And while Curiosity keeps on looking for more, we anticipate some great discoveries to be unveiled.


Windows 8.1 detailed: 12 key changes coming in the Windows 8 update!!!






1. Lock screen slideshow

"As people started using Windows 8, we found that people were using their Lock screens to show pictures of their families," Leblond says. So in Windows 8.1, you can turn your PC or tablet into a picture frame by making your Lock screen a slide show of your pictures - either locally on the device or photos from Microsoft SkyDrive. "We also added the ability to take pictures with the built-in camera right from the Lock screen without having to log in."

2. More backgrounds

Windows 8.1 offers more colours and backgrounds for the Start screen - including some with motion. You can also choose your desktop background as your Start screen background.

3. Different tile sizes

As in Windows Phone 8, the Windows 8.1 Start screen features a variety of tile sizes including a new large and new small tile. It's also even easier to name groups and rearrange tiles, says Leblond: "We found people were accidentally moving tiles on their Start screen so in Windows 8.1, you press and hold (or right click) to move things around." You can now select multiple apps all at once, resize them, uninstall them, or rearrange them: "View all apps just by swiping from the bottom to view all apps, and we've added the ability to filter your apps by name, date installed, most used, or by category. You want the Start screen to be about all the things you love. So when you install a new app from the Windows Store, we no longer put that app on your Start screen. Instead, you'll find these apps under apps view as mentioned above and marked as 'new' where you can choose to pin the apps you want to your Start screen."


4. Aggregated search


Instead of having to select an app and then search when you go to the Search charm, Bing now powers an aggregated search system from the web, your files, SkyDrive and elsewhere. Leblond says: "We think this will really change the way you interact with the Web and with Windows making it quicker and easier to get things done. It is the modern version of the command line! Results from local files, apps, and settings are easily accessed in the same convenient view by scrolling to the left."

5. Enhanced apps

New app enhancements are also promised to all the built-in apps. According to Leblond: "The Photos app now has some new editing features that let you quickly edit or adjust photos when you view them in the Photos app or open them from other places like the Mail, SkyDrive, and Camera apps. And our Music app has been completely redesigned to help pick and play music from your collection. We plan to talk more about updates to the built in apps in Windows 8.1 and some brand new apps we will be introducing in [the] future. We're also making improvements for using multiple apps at once in Windows 8.1."


6. More snap views

If, like us, you use Windows 8 a lot, you'll have been frustrated by the lack of 50:50 split snap views. This is the game-changer for Windows 8 apps. "You will have more ways to see multiple apps on the screen at the same time," says Leblond. "You can resize apps to any size you want, share the screen between two apps, or have up to three apps on each screen if you have a multiple displays connected, you can have different Windows Store apps running on all the displays at the same time and the Start Screen can stay open on one monitor (yes!). This makes multi-tasking even easier. Also in Windows 8.1, you can have multiple windows of the same app snapped together - such as two Internet Explorer windows." We're really looking forward to that.


7. An enhanced Windows Store

App updates will now install automatically in the background as they come through the Store. And search is available in the upper right hand corner for finding the apps you want. Leblond elaborates: "The improved Windows Store is designed to show more info than before in Windows 8 with detailed lists of top free apps, new releases, and picks for you on the homepage. The app listing is more descriptive and informative and includes an area for related apps to help with app discovery."

8. Save direct to SkyDrive, plus offline files

In Windows 8.1 your files can be saved directly to SkyDrive. The SkyDrive app will also get a new update so that files are available even when offline - as in the desktop version.


9. You no longer need the desktop Control Panel

The updated PC Settings in Windows 8.1 gives you access to all your settings on your device without having to go to the Control Panel on the desktop. "You can do things like change your display resolution, set power options, see the make and model of my PC, change the product key, let me do Windows Update, and even join a domain – all from PC Settings," says Leblond. You can also manage SkyDrive from PC Settings as well.

10. A new Internet Explorer

Internet Explorer 11 will ship with Windows 8.1. "IE11 will offer even better touch performance, faster page load times and several other new features we think you will enjoy," says Leblond. "For example, you can now adjust the appearance of modern IE11 to always show the address bar and you can have as many open tabs as you like. And you can access your open tabs in sync across your other Windows 8.1 devices."

11. Better with a mouse and keyboard


For devices without touch, Windows 8.1 features a number of improvements for easier navigation using a mouse and keyboard. "PCs today are evolving for a world of mobile computing where people interact with their devices through touch, and we designed Windows 8 for this," explains Leblond. "But we also recognize there are many non-touch devices in use today - especially in the commercial setting."

12. A change to the Start 'tip'


You've already heard about this one, right? Leblond adds that there are also options to change what the corners do, and options to boot into alternate screens: "For example, if you prefer to see the Apps view versus all the tiles, you can choose to have the Start screen go directly to Apps view."

Microsoft says it will be releasing more Windows 8.1 details "in the coming weeks. As you've heard us talk about before, Windows 8.1 will be available later this year as a free update."

Microsoft also says that it will also be sharing more about Windows Embedded at Build. Embedded will be
 "updated in the same timeframe as Windows 8.1. We're aligning the platforms even more to bring Windows to form factors of all types, including not only tablets and PCs, but also the growing category of devices such as ATMs, point of service (POS) terminals, and kiosks."





Did our first glimpse of Metro Office apps just appear in Microsoft's Windows 8.1 pics?





Microsoft let many cats out of myriad bags in its whopping 1,817-word reveal of Windows 8.1 yesterday, but it's what the company didn't talk about that's almost more intriguing. Mixed in among all the chatter was a curious screenshot of the Windows 8.1 Start screen, and tucked away in amongst its Live Tiles were four eye-opening squares.


Folks, I think we just got our first look at modern-style Office apps. Or at least their Live Tiles.



Modern Office apps


 

Check out the image above, from Microsoft’s own Windows 8.1 blog post. Word, Excel, PowerPoint, and OneNote all make an appearance, positioned there next to the SkyDrive app.

So what, you ask? Microsoft owns Office! Indeed it does—but Microsoft does not offer modern UI versions of its core Office programs. Word, Excel, PowerPoint, and OneNote are only offered as desktop programs as of today. And pinning those desktop productivity programs to the Windows 8 Start screen creates tiles with the same light blue background as any other desktop app—and not the colorful squares shown in Microsoft's blog post.

Microsoft does offer a modern app for its Lync communications software, though, and its Start screen tile bears a striking resemblance to the Office app tiles in the Windows 8.1 blog post, from the simple colors to the "open book"-style design.



In the screenshot to the right, you’ll see tiles of Microsoft’s modern Lync app alongside tiles for the core Office desktop programs, all from my Windows 8 Start screen. See what I mean? 





Now, the appearance of colored Office tiles in Microsoft's blog post could just mean that we’ll have the ability to choose background color for tiles derived from desktop programs, which would be pretty cool in and of itself. (Update: And apparently the case, according to Foley's Tweet. Microsoft's blog post and the subsequent coverage said nothing about customizable tile colors, so hey, the appearance of those tiles nonetheless brought something new to light. -Brad) 





But consider that no other desktop program was shown in any of Microsoft’s Windows 8.1 screenshots... and the four tiles' close resemblence to the Lync app's tile, and the Start screen tiles for Microsoft's other preinstalled such as Video, Music, and Maps... and that those intriguing  modern-style Office “Gemini” rumors  have been floating around.

Suddenly, the Office tiles in the Windows 8.1 screenshots start to look like a lot more than mere squares. We may know for sure soon. If the Gemini rumors hold true, modern-style Office apps may just land on Start screens around the globe later this year

Hands on with the new Razer Blade, a gaming Ultrabook thinner than a Macbook Air!







Razer's latest Ultrabook is a wake-up call. It's a warning shot across the bow of Apple, Samsung and other manufacturers of premium thin-and-light laptops. And its message is clear: "Look at me." 




Look at how a gaming laptop that's thinner, lighter and more powerful than a Macbook Air can be built and marketed to consumers. The new Razer Blade is a piece of premium hardware with an equally premium price tag. And it's also an expensive wager that people will pay $1,800 or more for a Windows 8 Ultrabook designed explicitly for PC gaming—all while the PC market is hemorrhaging money. 




The Razer Blade is the thinnest, lightest gaming laptop we've ever seen.



That’s right, the new Razer Blade laptop, announced at a special Thursday press event in San Francisco, is no longer the 17-inch behemoth we once knew and (mostly) loved. That old model has been renamed the Razer Blade Pro to make room for the new Razer Blade, a 14-inch gaming machine with 8GB of RAM, an upgradeable 128 GB SSD, a discrete Nvidia GTX 765M GPU and a “fourth-generation” (read: Haswell) Intel CPU packed into an aluminum body that’s barely two-thirds of an inch thick. 




The whole package weighs in at just over four pounds and sports the sort of connectivity options you'd expect from a contemporary ultraportable, including three USB 3.0 ports, an HDMI out, an 802.11 wireless adapter, and a Bluetooth 4.0 radio. The Blade will be available for pre-order on June 3rd, and while the price starts at $1,800, you can expect to pay more for models with a bigger hard drive. 





The new Razer Blade is very, very thin. Our hand model wants you to know that the bottom can also get very, very hot.
 


Razer says this new and improved Blade is the world’s thinnest, most powerful gaming laptop, and while I’m going to steer clear of vouching for the unit’s performance until we get one into our lab for thorough testing, I’m happy to report the Blade demo units we tinkered with during Razer's Thursday event were incredibly thin, remarkably light, and scorchingly fast. 



The new Blade feels like a MacBook Air without the sharp edges, though its sleek, matte black aluminum case feels a little flimsier than the MacBook Air’s aluminum unibody. The power adapter looks equally sleek in promo shots, and I poked around underneath our demo station to verify that, yes, the new Blade power brick is just as tiny as the adapters that power the old Razer Blade and the Razer Edge. 




And if it seems a little strange to praise a laptop for its lightweight power adapter, well, you’ve probably never had to lug a laptop back and forth across the country. 




The screen on the Razer Blade looks good when you're facing it dead on, but it looks washed out from almost any other angle.



 
Anyone who's carried a laptop during a cross-country expedition can also appreciate the value of a bright, sharp and (most importantly) shareable screen. The Razer Blade’s 14-inch, 1600-by-900 resolution screen does most of that, delivering crisp, vibrant images under fluorescent office lighting, but only if you have the screen tilted just right. The optimal viewing angle on the Blade is pretty narrow, and colors quickly invert and wash out if you stray too far beyond it.



During our demo, I played through a tense underground fight sequence in Metro: Last Light, which ran smoothly on high settings at the Blade’s native resolution. The deepest blacks of the underground tunnels looked a bit faded on the Blade’s screen, but that may be no fault of the hardware, as PC demo units often have their brightness settings cranked up to maximum to catch your eye across a crowded conference room. The new 14-inch Blade also lacks the customizable OLED Switchblade keypad that graced the original Razer Blade, presumably due to size constraints. 



Razer put out this promo shot to remind you that yes, despite naming their new 14-inch laptop the Razer Blade (pictured left), the old Razer Blade (on the right) is still available as the Razer Blade Pro.


 

The original 17-inch Razer Blade laptop isn’t going anywhere. Razer rechristened it the Razer Blade Pro, and it's been spruced it up with the same CPU and GPU that power the Razer Blade, along with slew of new Switchblade templates for productivity apps—Photoshop, Premiere and the like. 



Razer is also slashing the price of the Razer Blade Pro down to $2300, and selling it at an even deeper discount of $1000 to independent game developers with successful Kickstarter campaigns as part of Razer’s new developer outreach program. Dubbed the Razer Education/Indie Discount program, it offers Razer products at discount prices to creative professionals—game developers, game design students and development staff—who successfully apply via the Razer website. 




Debuting a premium Ultrabook in a PC market with an uncertain future is a bold move, but this isn't the first time Razer has pushed into a new market with high-priced hardware—the company built its reputation as a source of premium PC gaming hardware with quality mice and keyboards, then expanded into headsets and controllers before plunging into the shrinking PC market with the original Razer Blade gaming laptop and the Razer Edge Windows 8 tablet. 




The overpriced hardware gambit must be paying off, too. Razer shows no signs of being eager to leave the premium PC-building business. We'll find out if that confidence is warranted when the new Blade Ultrabooks start shipping in June. We can't wait to get one in for a final review.


Asus crams 4K resolution into a 31.5-inch Ultra HD monitor!!!






Just in time for the Windows 8.1 debut and its hinted-at 4K resolution support, Asus is announcing a professional-grade (read: not cheap) Ultra HD LCD monitor.



The company will show the PQ321 Ultra HD, a 31.5-inch 4K Ultra HD monitor featuring a maximum resolution of 3840 by 2160 at Computex in Taipei, which starts Tuesday. The unit has a 16:9 aspect ratio, 176-degreee wide viewing angle, DisplayPort, dual HDMI inputs, and built-in 2W stereo speakers.



More pixels (per inch)


Asus said it used Indium Gallium Zinc Oxide (IGZO) for the active layer of the PQ321’s LCD panel instead of the standard amorphous silicon for LCD displays. Because IGZO panels can work with smaller transistors, Asus could cram smaller pixels onto the screen. That’s a good thing considering this panel has four times as many pixels as a standard 1080p monitor. 



The PQ321’s 140 pixels per inch may not sound great in an era when the iPad and other tablets have 264 ppi or more. But keep in mind a standard 1080p monitor with the same dimensions as the PQ321 would have exactly half the pixels per inch of Asus’ Ultra HD monitor.



Asus did not announce pricing or an official release date for the PQ321, but Hexus and Engadget both report that the monitor will debut in North America at the end of June.



Once you can buy Asus’ snazzy new monitor, however, what puts it to best use? Both the Xbox One and the PlayStation 4 will support 4K resolutions, and with the PQ321’s built-in speakers, using this monitor as a TV replacement should be a snap.



If you’re looking to do some PC gaming at 4K resolution, you’d better be prepared to shell out some serious dough—Not only for the monitor, but high end specs for your gaming box as well. A good start would be a high-powered graphics card like AMD’s $999 Radeon 7990.



Movies emerge


Gaming may be the first, best use for a 4K monitor. The next obvious choice is movies, but since 4K resolution has yet to go mainstream, finding 4K titles could be difficult. In late 2012, Sony released a hard drive containing ten 4K movies to buyers of its $25,000 84-inch 4K UHDTV. The company is also releasing classic movies remastered in 4K such as Glory, Taxi Driver, and Ghostbusters. 




Sony calls them "mastered in 4K" and ships the films on standard Blu-ray discs, but they're not really 4K technology. For starters, current Blu-ray discs max out at 1080p resolutions. So what you’re really getting are movies that were mastered at 4K in the editing suite, but play back at home at 1080p. That said, you may notice a small bump in picture quality such as color, detail, and contrast compared to standard Blu-ray discs. The labeling clarifies that they are "optimized for 4K Ultra HD TVs." 




An Ultra HD monitor sounds great, but there probably isn’t a ton of use for it yet unless you’re a serious gamer or looking to do graphics or video editing. But if Asus pushes the price low enough—which is reeeeeeeeally unlikely right now—you could pick up a PQ321 as an
investment in the seemingly inevitable 4K future.
 

How to reduce your office printing costs!!!






HP's ultra-fast 60ppm inkjet has low running costs of 2.0p and 5.3p for ISO black and colour pages



Get any two business people talking about printing and within minutes they'll be bemoaning ink and paper costs. The price of the printer is a one-off and soon slips into the mists of office history, but constant replenishment of consumables keeps reminding you of the true cost of printing.


It's a cost you can't avoid completely and is directly proportional to the number of documents you print. But there are things you can do to mitigate the costs, some of which are free and others cost little.



There are a number of features built into virtually every printer that can be used to reduce running costs. Which ones you choose to use are up to you, but all will control the use of one of two things: ink or toner and paper.
 


Ink/toner


The largest savings are in reducing ink/toner use, and the most obvious step is to use draft print mode wherever possible. This is a setting in the print driver, which can be accessed, for example, through the small Print Properties link on the Print page of recent versions of Word.



Draft mode works by printing selected dots from the full matrix that's printed in normal print mode. This gives a lighter and dottier appearance to text, but in most cases, it's still perfectly readable and is fine for day-to-day office use.



It usually increases print speed too, so there's a double gain.



Some printers offer an 'ink-saver' or 'toner-saver' mode instead of a true draft, which isn't normally quicker than normal print and some, particularly older Epsons, use a different default font for draft text print, which may make slight changes to the layout of pages.



You can save money by using third party inks and toners, although printer manufacturers try to deter this by voiding warranties and linking their cartridges to their machines electronically. From our testing, we consistently see better quality print using manufacturer's cartridges than with third parties, but some third party products, like those from www.stinkyinkshop.co.uk, come close.
 


Paper


If you print a lot of documents, paper costs will also mount up, with a ream of paper typically costing between £3 and £5. But paper savings are also easy to achieve on most printers.



More and more machines offer duplex print, where pages are printed on both sides of the paper. Each time you print duplex, you save close to half your paper costs, between 0.5p and 1.0p per page, depending on paper.



For internal office documents, you can also print more than one page per sheet. Most printers have facilities to do this automatically and printing even two pages per sheet, where for instance you print two A5 page images on an A4 page, is a useful saving, over time.



Multiple pages per sheet require original text at a reasonable size, otherwise it can be hard to read.



Combining duplex and multiple pages can also work well. A long, single-side A4 document can be reduced to a two-sided A5 booklet, saving 75% of the paper in the process.



It may be obvious, but you can always save money by looking at the cost when selection papers. Don't feel you have to use specialist inkjet or laser paper for day-to-day work; many cheaper papers work well, including multi-use types, designed to work in both types of printer.



Buying one paper for all your office printing can provide extra economies of scale.

 


Better draft

 

If you want to use draft print but your printer's draft output is particularly dotty or poorly formed, you could use EcoPrint 2. This is a commercial program, costing $40 (£26.50), or $60 (£40) for the Pro version, which provides a good quality draft print for which you can select the amount of ink/toner saving you want.


With savings of between 10% and 50% it gives lighter prints, but with very little degradation in the quality of text and graphics.



If you have sufficient funds, it's always worth buying the high capacity XL versions of cartridges. Although these can be up to double the cost of the regular consumables, they give back more than this in extra pages printed.
 



Before buying


As well as checking that any new printer you're considering supports features like duplex print and multiple pages per sheet, you should do a little calculation. In general, the higher the asking price of the printer, the lower the running costs per page.



What you need to know is how many pages you'll have to print to make back the extra cost of a more expensive printer.



Here's an example: say you print about 1,500 pages a year, made up of 1,000 black and 500 colour. You're considering two printers (we'll use inkjets in this example): one costs £130, with page costs of 3.7p black and 11.9p colour, including 1p paper; the other costs £190, with pages costs of 2.1p and 5.3p.



Over the three years life of your printer, the total cost of ownership (TCO) of the first will be £420, while the second will have a TCO of £333, nearly £90 less.



If you keep your printer more than three years, or print more than 1,500 pages per year, the difference will be even greater.



Using these few, simple ideas, you can make significant savings to your overall printing costs. You needn't feel so much at the mercy of suppliers who know the real money is not in the printer, but in its inks or toners.


Panasonic Toughbook CF-19 business laptops! -10






Panasonic Toughbook CF-19


From £2,400



The Panasonic ToughBook is a bit of an anomaly on this list. It's not sleek or light, doesn't boast an HD display and still runs Windows 7, albeit the professional version. But it's tough as the proverbial coffin nail and if your work involves spending any considerable amount of time outside, it's the only logical choice.



The 10.1-inch display will rotate and fold down creating, effectively, a tablet that measures 51mm thick and weighs 2.3kg.



Panasonic hasn't changed the ToughBook's chassis since it revealed the machine back in 2007 and it remains water and dust proof as well as shock resistant. Rubber flaps cover all the vital ports to keep the dust and debris of the outside world away from the internals.



Specs-wise, Panasonic has included an Intel Core i5-3320 processor and 4GB RAM and a battery capable, it says, of 10 hours of usage. Certain new features have been added, such as a USB 3.0 port and the CF-19 also has the option of 3G broadband if you don't have Wi-Fi or a hard wired internet connection.



Admittedly, this is a niche product with an exceptionally high price point and won't be suitable for the majority of scenarios. But if you're looking for a rugged work laptop to survive overseas fieldwork or life on a building site, then this is the machine.



Asus VivoBook S400C business laptops! - 9






Asus VivoBook S400C


From £454



It was a difficult choice to include the VivoBook S400Cover Asus' more powerful Zenbook U500 but ultimately the former's balance of performance and price won out. The 14.1-inch S400C features a full capacitive touchscreen, albeit with only a 1,366 x 7.68 resolution.



The dual-core Intel Core i3 processor and 4GB RAM don't offer much in performance terms and other machines on this list will easily outstrip the S400C when it comes to raw power. However, you get a generous 500GB of hard drive storage and all the requisite ports including USB, VGA, Ethernet, HDMI and an SD Card reader.



What's more, the VivoBook S400C is actually a very well made and attractive laptop. The chassis is just 20mm thick and has a black, brushed aluminium lid that compliments the silver elsewhere on the laptop. There's a chiclit keyboard that's comfortable for typing and the three and a half hour battery life is pretty reasonable as well.



At this price, you can't expect much but extra features in the form of Asus' SonicMaster audio technology and, of course, the touchscreen help to make this a good choice. If you're after an all-rounder that looks nice and won't break the bank, the VivoBook S400C could be worth a look.



Toshiba Satellite U940 business laptops!- 8






Toshiba Satellite U940


£599



The Toshiba Satellite U940 is one of the few business laptops on this list that doesn't feature a touchscreen. That helps to keep the price down to sub-£600 and means that if you don't particularly want or need a touchscreen in a new laptop, it could be worth exploring.



It's also worth pointing out that at 1,366 x 768, the 14-inch screen will only manage 720p HD playback. However, what you do get is some pretty reasonable performance considering the price. The Satellite U940 comes with an Intel Core i5 processor (which can be scaled down to an i3 if you want to keep costs down further) with 6GB RAM. There's a 750GB hard drive and a 32GB SSD which means this has the benefit of both fast boot-up and plenty of storage.



There are plenty of ports and connections on the 1.79kg frame including two USB 3.0 ports, one USB 2.0 port, HDMI and Ethernet connections and an SD card reader.



The Satellite picks up points for having a comfortable, well-sized keyboard and trackpad, making it good for prolonged typing. Unfortunately, it loses some of those points because, although the plasticky, industrial blue chassis feels solid enough, it hardly looks attractive.



Acer Aspire S7 business laptops! - 7




Acer Aspire S7


From £899



Acer's Ultrabooks have been steadily getting better and its most recent, the Aspire S7, stands as an excellent choice for a business machine away from the office. The Full HD 13.3-inch touchscreen is bright with exceptional clarity and the use of a middling Intel Core i5-3317U processor and 4GB RAM allows it to stay shy of the £1,000 mark.



The Aspire S7 is extremely portable at only 1.3kg and measures only 11.9mm thick. It's one of the best looking Ultrabooks here as well, with a white Gorilla Glass 2 chassis, soft backlit keyboard and large integrated trackpad.



Ports are pretty scarce due to the size, but you're still afforded two USB 3.0 slots, a Micro HDMI port and a card reader. The only shortcoming here is the lack of an Ethernet port.



Apart from the aesthetics, the Acer Aspire S7 can also boast of a strong battery performance, offering a quoted 12 hours of life that is more likely around eight hours in real time usage.



Admittedly the price is still a little high for an Acer machine and the processing power isn't as good as some of the other machines on the list, but the Aspire S7 more than makes up for that in looks and portability.



Lenovo ThinkPad X1 Carbon Touch business laptops!- 6







Lenovo ThinkPad X1 Carbon Touch



From £1,455



The ThinkPad X1 Carbon is Lenovo's flagship business laptop and now the Chinese company has improved the model by adding a touchscreen to run with Windows 8. This has the effect of bulking up the chassis slightly to 21mm thick and 151kg in weight, but it's as durable as ever and the carbon fibre casing can easily withstand a knock or two.



Power users won't be disappointed as Lenovo will let you choose either an i5 or i7 processor with up to 8GB RAM and a 180GB SSD. The 14-inch display is a ten finger multitouch screen with HD+ resolution and anti-glare coating that means you can work in brightly lit environments without irritating distractions.



Where the Carbon Touch really comes into its own is the array of business-friendly features that Lenovo has included. Along with a fingerprint scanner, there's RapidCharge technology to effectively charge the machine from dead in 45 minutes, and the battery itself will give you a good seven hours of usage from a full charge.



It's not perfect – the integrated graphics card isn't up to the task of heavy graphics processes like professional editing software. But Lenovo offers an excellent three-year warranty that might sway you towards this machine.


Samsung Series 9 NP900X3D business laptops! - 5





Samsung Series 9 NP900X3D


From £850



Designed for portability over everything else, the Samsung Series 9 NP900X3D is a stunning piece of craftsmanship that will suit you well if you're constantly travelling for work. The chassis is only 13.2mm deep at its thickest point and at 1.13kg you can almost forget you're carrying it.



Samsung has fitted the latest Series 9 with a 13.3-inch 1,600 x 900 display that uses SuperBright technology to light the screen at 400nit. An integrated light sensor regulates the brightness of the display and the backlit keyboard depending on the ambient light. If you're regularly taking the red eye flight to New York and back, this is the laptop you'll want.



But it has its downside: the price is a little steep, there's no touchscreen and the processor is only Intel Core i5 level. The latter hasn't been updated from Intel's last generation and the integrated graphics are limiting for graphics heavy work.



Unfortunately, the thinness of the chassis comes at the expense of connectivity as you'll only find two USB ports, a 3.5mm headphone jack, memory card reader and a micro HDMI port. The specifications may leave something to be desired but if you avoid bulky laptops like the plague, then this will be an attractive purchase.

Dell Inspiron 15z business laptops! - 4





Dell Inspiron 15z


From £659



Dell's Inspiron series has served us well over the years, and the company has now updated its Inspiron 15z model with Windows 8 and a 720p touchscreen. It strikes a reasonable balance between affordability and performance and the option to customise your order gives you even more freedom when buying.



The price we've quoted gets you an Intel Core i3-3217U processor running at 1.8GHz and backed with a more than capable 6GB of RAM. There's also 500GB of storage space accompanied by a 32GB mSATA SSD that's responsible for booting Windows 8 as fast as possible.



The Inspiron 15z also features the DVD optical drive that's becoming something of a rarity for laptops these days. If you've still got programs and data on CDs then this will no doubt be an important choice for you.



The other reason we're recommending the Inspiron 15z as a business laptop is that the build quality is first class and very reliable. The silver aluminium chassis is understated and free from unwanted flexing or rattling. You'll also find the keyboard and trackpad are very comfortable to use for extended periods of time.





HP Pavilion 14 Chromebook business laptops! - 3






HP Pavilion 14 Chromebook



£250

 

At first glance, Chromebooks might not hold much appeal, as they essentially require an internet connection to work. However, many Google apps can now be configured to work offline, and if you're simply looking for a cheap way to get some emails done on the train or check the next day's presentation at home then this is an excellent way of doing so.



The HP Pavilion 14 uses a 1.1GHz dual-core Intel Celeron 847 processor and comes with a 14-inch screen at the standard 1,366 x 768 resolution.




It weighs 1.8kg and, like other Chromebooks, is constructed from plastic to keep the costs down. However, the 2GB RAM and 16GB SSD are more than capable of running web-based Chrome and you're given three USB ports, 10/100Mbps Ethernet and 802.11n Wi-Fi



.
For general usage, you'll get around four and a half hours from the Pavilion 14's removable battery, and HP has even seen fit to include Altec Lansing speakers for playing music. If you want a budget machine to keep up with work outside the office and can be reasonably sure of a constant internet connection then this is well worth a closer look.


MacBook Pro with Retina Display business laptops! - 2






MacBook Pro with Retina Display

 

From £1,999


If you're a creative designer or work in the graphics industry then the MacBook Pro is going to be near the top of your list for a work-based laptop; but the staggering graphical power and screen resolution is matched by the astronomical price.





The top specification arrives with a 2.7-inch quad-core Intel Core i7 processor and 16GB of DDR3 RAM and 512GB of flash storage.




Graphics are supplied by an Nvidia GeForce GT650M with 1GB of dedicated video memory that backs up the Intel HD Graphics 4000 integrated chip. Apple has included both Thunderbolt and DVI digital video output that lets you attach up to four extra monitors to the MacBook Pro for a complete professional setup.




Even without the extra monitors, the 2,880 x 1,800, 220ppi display on the 15.4-inch screen is breathtaking and ideal for filmmakers, game designers or anyone else who needs the best screen money can buy.




All that technology brings the MacBook Pro in at 2.02kg and 9.7-inches thick.




The price precludes this being a realistic purchase for all but the most demanding of professionals. But it undoubtedly deserves a spot in our list.


Sony Vaio Duo 11 business laptops! - 1






Sony Vaio Duo 11

 

£1,149


The only hybrid device on our list, the Sony Vaio Duo 11 is an exceptionally powerful sliding Ultrabook that doubles as a full featured Windows 8 tablet.




One of its highlights is an 11.6-inch full HD IPS touchscreen display, which also provides also the main navigation method as there's no touchpad, merely an optical nubbin stuck into the keyboard.




If you're looking for portability this is going to be of interest, although we have to point out that at 1.3kg, the Duo 11 is about the same weight as a standard laptop. However, the tapered edges and classic Vaio styling mean it's certainly a looker and won't fail to draw heads in the boardroom.




Performance and connectivity haven't been left out. At the entry level configuration at the price we've quoted above, you'll find an x86 Intel Core i5 processor with integrated graphics and 4GB of RAM.




The speed comes from the 256GB SSD storage space and Sony has fitted the Duo 11 with two USB ports (one of which is the faster 3.0 format), HDMI, VGA and Ethernet ports as well as an SD card slot.




The caveat to this machine is that battery life could be improved. Sony quotes up to six and a half hours, but in real life don't expect more than about five.

Apple iPhone Sales Grow By 400% In India; iPod Touch Becomes Cheaper!!




                The immensely successful, Steve-Jobs inspired Apple product 'the iPhone' is making it big in India. Thanks to the EMI as well as cash back schemes offered, Apple India's monthly iPhone sales have risen by 300% to 400% over the last few months. To quote the numbers, the iPhone sales are now nearing 400,000 units per month in India (analysts at Credit Suisse share). That is huge. How is this news significant, you ask? Well, it is the fact that the budget-driven, low-end feature phone prone audience in India no more seems to be perceiving the iPhone as a high-end product. It has become an affordable option for the masses. More importantly, this news coincides with another mind-boggling headline from Apple - the launch of a budget iPod Touch.



              Yep, Apple has launched a cheaper 16 GB iPod Touch that doesn't feature the rear-facing iSight camera for $229, which is $70 cheaper. Though the new iPod touch has the same tech specs - a 4-inch Retina display, a dual-core A5 processor, and a front-facing FaceTime HD camera for video calling, it now comes in just one color — grey with a black front.




               So, it seems Apple is growing by leaps and bounds in India. The key to its success is its super aggressive pricing and and the advertising mania it has created. You can rarely go through a fresh copy of newspaper or a TV channel without seeing an advertisement about the iPhone 4 and iPhone 4S older models. It is interesting to note that those are not sold in any other country and have surprisingly created a strong foothold for iPhone as a product in India.




              What do CEans here have to say about this news? We would like to know, so speak up in the comments. And not to miss - if you are looking forward to buying the new iPod touch, know that it is shipping 'within 24 hours' if you live in the United States, or you can pick it up at an Apple retail store starting tomorrow, May 31.
