There is another competitor in the tablet computer race.

Microsoft has unveiled its "Surface"; a competitor to Apple's iPad.

One difference is the Surface is a tablet that can operate like a full PC running windows-- microsoft's dominant operating system.

Surface has a touch screen just like the iPad, but has a unique case with a built-in kick stand.

Surface weighs under 1.5 pounds and is slightly smaller than its Apple competitor, though with a bigger screen.

The Microsoft tablet is expected to go on sale sometime this fall and  cost about the same as the iPad
