Windows 8 is loaded with support for numerous gestures. These gestures are mostly aimed at tablets and touchscreens, but they work pretty well on notebook touchpads. We've started seeing desktop keyboards incorporate Win8-friendly touchpads, as well. The first one popped up in Japan with a premium price tag. Now, a more affordable example is headed for North American shores. Say hello to Genius' SlimSar T8020, which is selling for only $37.
