Tiles
Windows 8 features tiles that display more information than traditional icons.
Start Screen
Windows 8s start screen offers a variety of quick-glance information, including (at least, based on this screen) time and date, and emails and conversations.
Touch-Sensitive
Microsoft plans to port Windows 8 onto a variety of devices, including the tablet and PC form factors.
Apps
Microsoft offered a glimpse of a few new applications at work, including this News one.
Horizontal
As with Windows Phone, the Windows 8 interface seems to emphasize a horizontal format, with the ability to scroll left or right to see new information.
Mouse and Keyboard
Windows 8s user interface is also navigable with the traditional mouse-and-keyboard configuration.
Swiping
Here is a shot of Windows 8 finger-swiping in action.

Snap
Like Windows Vista and Windows 7, Windows 8 lets the user snap content to the sides of the screen—in this case, a secondary application running alongside the main one.
