From the description it sounds pretty much like the handheld device I use that turns 'any surface into a touch screen'. Now it could just be my general germ phobia, but I go out of my way to avoid touching most surfaces in public.. so I am not convinced on that side either. That said, if it will make me more productive by replacing the mouse mentioned above and without interfering with typing, I will give it a try. Am I hopeful? Nope.
