The Diatec SmartTrack Neo USB touch pad adds multitouch functionality to PCs, which is perfect timing for the upcoming release of Windows 7. The touch pad is roughly 3 inches wide and an inch long and features two buttons on the bottom as well as a single USB cord that connects it to a computer. Once installed, the device supposedly enables pinching, pulling, swiping, and turning, much like the motions on an iPhone, and it even responds to gestures with more than one finger. Unfortunately, the Web site indicates that the hardware is only compatible with PCs, so Mac Pro, iMac, and Mac Mini users can resume breathing.
