Microsoft was on the floor of CES 2012 with a copy of Windows 8 Pre - Beta 8175 on a tablet.
Microsoft are hard at work developing Windows 8 to make the Windows 8 Beta release date in late February.
As a result, not that much was shared during CES. A few tweaks here and there, a few charms. Basically we will have to wait for Canouna or the Beta. Whichever comes first.
Nothing that radical to report but check out this video from Tom Warren at the Verge.
