Your mouse can, at times, dictate your sitting position and posture while you work. Imagine being able to just slip your mouse over your finger though and being able to just sit back and relax while you edit that report. I really like to sit cross-legged (like a little kid). I can see myself being able to do this comfortably now. Probably bad for back in some way though. Getting old sucks.

This is the wireless mouse that slips onto a forefinger like a ring for easy control of a computer’s functions during presentations. In addition to "left" and "right" mouse buttons, its thumb touch pad uses a patented optical sensor with 1,000-dpi sensitivity, providing eight-way scrolling. It communicates from up to 30′ away over an interference-free 2.4 GHz radio frequency with a receiver that plugs into a computer’s USB port.
