On october 26th Windows will release its tablet the Surface RT along with Windows 8. Three days later, the Windows 8 phones will be released. What’s truly remarkable about Windows 8 is the integration of all Microsoft devices (PCS, tablets, phones) under one OS; you can easily synchronize all your files to all of your devices.
Windows 8 marks a drastic UI change for Microsoft as it ditches the old start menu and usual desktop UI with a new, highly-interactive panel interface. The panel concept is innovative, but personally I don’t think it makes a whole of sense on a desktop.
With that being said, Windows 8 is more appropriate for touch-enabled devices such as the Windows phone and the Surface tablets. The Surface RT, to be released this Friday, will run a specific version of Windows 8 called Windows RT. Windows RT is ARM-based so a disadvantage is you cannot run use older versions of applications that were meant for x86. Therefore you will be limited to apps available on the Microsoft Windows store.
The full x86 version Surface PRO, will have the capabilities of any other laptop or desktop and will be available early 2013.
