The front sports a glass surface with three capacitive buttons and the back showcases the company's Crystal Reflection process -- an attractive patterned glass-like finish that's a bit of a fingerprint magnet.
While the Mobile Mouse has just the Start key and a scroll wheel, though, the bigger Comfort Mouse takes things a step further: the button there doubles as a capacitivesurface you can swipe to toggle through open programs in Windows 8.
The capacitive display can recognize orientation, letting you drop the controller in any position throughout the surface, then outputting a map to match.
