Grown Tablet market globally



According to the latest data from market research firm IDC, the worldwide tablet market grew by around four per cent to 50.4 million tablets in the first quarter of 2014 and is in lower growth than previously. One of the main reasons are smartphones with larger touchscreens and the second reason are tablet users keep their current tablet longer instead of purchasing a new model. The U.S. technology company Apple, with a market share of 32.5 percent, and its iPad tablet is still the leading providers among tablet manufacturers.

In the second place Samsung landed with a rise of 4.8 per cent market share. His position in the market would expand by an attractive pricing policy, smartphone packages and a stronger cooperation with mobile operators on the South Korean company. On the tablet market Windows tablets occupy a subordinate role and increase their market share slowly. In the tablet operating systems Google Android is the leader, as it is located on 66 percent of mobile devices.

Windows XP is over

Windows XP goes. The operating system of Microsoft, launched on 25 October 2001 , we said goodbye. Redmond today issued a last fix pack (the famous patch Tuesday) and urges the ultimate users of the operating system to migrate to a newer version of Windows . Microsoft gave a press conference yesterday evening, while focusing on its plans for Windows 8.1 and Windows Phone 8.1 update, also reported on the risks faced by users who still use the old OS.
On April 8, 2014 therefore marks the end of support for Windows XP. Microsoft will no longer publish any update of its operating system. Only companies can obtain updates from Microsoft updates sold at exorbitant prices because they require costly development teams. For the general public, no further update will be not released, except that published today. Clearly, what does all this mean? Here's a little summary of what you need to know:
  • If you still use Windows XP today, all is not lost. The latest patches from being published , you theoretically still a few days before the first security vulnerabilities of the OS will be exposed by hackers. But it is imperative to hurry.
  • The risk that the victim OS are significant security vulnerabilities are enormous. Windows XP is still installed about 27% of users worldwide, hackers already grind brains to discover vulnerabilities in the OS, which their will undoubtedly infect a machine, take control, to retrieve personal information from the remote user, etc..
  • It is imperative to migrate to a newer system . It may be Windows 7 or Windows 8.1 Update (or even Vista, why not) or a Linux distribution. Note also that, to switch from Windows XP to a much more recent version of the system, and without loss of data, Microsoft recommends the application Laplink PCmover Express .
  • If you wish to continue to use Windows XP temporarily, install a complete security solution. It will not protect you 100%, but will limit the damage until full migration.
  • Finally, perhaps more anecdotal, Office 2003 is also patched today for the last time. The office suite can also be a victim of security breaches, it is strongly advised to migrate to a newer version of Office, or failing version to opt for a free solution as Appache OpenOffice .
Finally, for more details, please see our big file on the migration of Windows XP to Windows 7 or Windows 8 , as well as our FAQs stop supporting Windows XP .

A touch pad holographic display

Soon, we can interact with a terminal via a holographic display . Finish the touch screen, instead, the tablet directly displays the data in the air through a holographic screen as interface.
The prototype was called AIRR Tablet for "Aerial Imaging by Retro-Reflection." The touch pad of a new genus is distinguished by its floating display. Allowing the user to manipulate and access to various applications. No need to use glasses virtual complete, the system is based on the retro-reflection to float interface and project information in the air. The tactile feedback is provided by sensors integrated movements, which can take up to 500 images per second. Touch holographic screen thus results in a specific order. Similarly, the user can enlarge or reduce the size via a simple gesture. This tablet was designed and developed by Professor Hirotsugu Yamamoto , University of Tokushima, Japan. At the moment, it is only a prototype that foreshadows the future of touch devices.

Windows 8.1 update 1: new preview mop Web


Since the beginning of the month, several Prerelease Windows 8.1 update 1 is out and about on the web. If they are distributed without the consent of Microsoft, they still allow you to make a serious idea next steps of the OS. For a few hours, a new pre-release is still at large. It is always WZor , who had already announced the release of the previous versions, which again prevents users via his Twitter account the diffusion of this . This is called MICROSOFT.WINDOWS.8.1.2014.UPDATE.X86-64.ONLY.MSU.9600.17025.WINBLUE_GDR.140214-1706-WZT . It is therefore an update applicable systems 32 and 64 bits . She dated 16.02.2014 and as in the previous edition, we must "tweak" a bit before installing this new prerelease. If little new compared to previous pre-release have yet been identified, it seems that OS is faster in the light of the first comments of users who have installed this edition. It is also likely that Microsoft is well advanced and that the bulk of the work was done, though Redmond has not officially communicated on this issue. It will anyway wait until April before Microsoft unveils its schedule during the Build.

In a new commercial touting Nokia for its new Windows Tablet Nokia 2520 in a funny scene which obviously compares the Nokia tablet with the iPad Air. Here, the competing tablet does of course not a very good figure. A preview of the Nokia tablet and a comparison to the competitors.

Battery life and features

The Nokia Lumia 2520 has a 8,000 mAh battery, which should, however, guarantee a five hours long battery life also promises the iPadAir long maturities and tests confirm a battery life of at least four hours even at high loads. A more fundamental strength of the Nokia Tablets is therefore probably the equipment and the ability to connect a keyboard.A full installed Office and Windows 8.1 RT make the tablet an attractive device to access while on the go all documents or to answer on the train to your next meeting before all messages. Other features of Nokia Lumia 2520: 2 GB RAM, 32 GB of flash memory, 800 Snapdragon quad-core processor with 2.2 Ghz. Alternative Tablets with Windows 8.1 come from Dell , Acer , Toshiba , MSI and of course Microsoft .

Nokia Lumia 2520 - Market launch in Europe?

In Europe, you have to wait a bit for the Nokia tablet. Market launch in Germany, Austria or Switzerland is not yet certain, if ever, the Nokia Lumia coming in 2520 not before 2014 on the market. In the U.S., the Nokia tablet is before Christmas in commerce, but whether in this country, the hybrid Tablets Nokia 2520 and Microsoft Surface are offered in parallel remains questionable.

Windows 8.1: the final version available for download


After months of waiting and various prerelease and RTM, the final version of Windows 8.1 was just released. The operating system is now available for existing users of Windows 8.0 in the form of a very large update to download.
To prevent all users, a message appears on the screen, inviting them to visit the Windows Store to get the full update. The update applies to the version for desktops and laptops (Windows 32 and 64 bit), but also for tablets running Windows RT. And even those who have a RTM version of Windows 8.1 are concerned, since update 241.3 MB (64-bit) is waiting on Windows Update.
Summary of previously discussed new features of Windows 8.1:
  • reintroduction of the Start button . Although very popular with users of older versions of Windows, its use differs. Left-click leads to the Home screen, and right-click to access the Control Panel, the Task Manager, the command prompt, etc..
  • ability to boot to the desktop (like Windows 7.0 and earlier versions) or on the Home screen (like Windows 8.0);
  • Total customization of the Home screen and access the list of installed at the bottom of the screen in question applications;
  • new Modern UI applications : health and fitness, alarm, calculator, etc..
  • new search module ;
  • Settings module PC much more comprehensive
  • full integration of SkyDrive and Office Explorer
Finally, the last point: the price. If you want to migrate from Windows 7 to Windows 8.1 , it will cost you $163.82. If you opt for the Pro version of Windows 8.1, it will cost you $382.43. Remember also that the sites Amazon and Darty always offer to migrate from Windows XP, Vista or Windows 7 to Windows 8 Pro for less than $60 ... and as the update to Windows 8.1, it would be a shame not to take advantage of this method, which drastically reduces the bill.

Computer carbon nanotubes the future of computing

The computer of the future will be smaller, fast, efficient and operate new materials. In this context, a group of American researchers created a prototype based on carbon nanotubes. Technology conceived as an alternative to the use of silicon, facing physical limits.

Presented as a graphene sheet rolled, the carbon nanotube is used here to create a new type of transistor. The computer developed by engineers at the University of Stanford is certainly rudimentary, it opens the way to more powerful but also energy-efficient machines. To achieve this functional prototype, the scientists had to overcome the major problems associated with the handling and assembly of carbon nanotubes. Indeed, they have imperfections that make their integration into electronic circuits. In the end, the computer with a processor consists of 178 transistors and clocked at 1 kHz. Each transistor contains 10 to 200 nanotubes. Also multitasking, it performs a basic operating system for counting and sorting numbers with the ability to switch between the two.
This computer is the first of its kind, but its designers are considering further research to develop models based on carbon nanotubes more sophisticated in the future.
