CEO Steve Ballmer was on hand to announce the tablet, calling it part of a "whole new family of devices" the company is developing.
The 9.3 millimeter thick tablet comes with a kickstand to hold it upright and keyboard that is part of the device's cover. It weighs under 1.5 pounds.
Steven Sinofsky, the president of Microsoft's Windows division, called the device a "tablet that's a great PC -a PC that's a great tablet."
