To take advantage of the touch features in Windows 7 and the upcoming Windows 8, Microsoft built a special mouse: the Touch Mouse. Similar to Apple's Magic Mouse, the Touch Mouse features a big touch-senstive area that can recognize one-, two-, and three-fingered gestures. Thanks to Microsoft's BlueTrack technology, you can use it virtually on any surface. Oh, and like most Microsoft mice, it's comfortable. There's one downside: it's only for Windows 7 and up.
