Following numerous rumors yesterday, Microsoft has officially unveiled a new tablet device known as Surface.

The device features an ultra-thin keyboard built into its screen cover, HD rear and front facing cameras, and a built in kickstand. There’s also a USB port and 10.6 inch ClearType HD screen. It’ll be available in a Windows RT and a Windows 8 Pro model.
