This is so weird - I've been wondering about Trackballs for years now! Does it really work that well? I can't see myself just rolling a little ball on a joystick base (just the way i look at it - I know tons of research has gone into the design to make it fit to your hand and all, but I just see a joystick base).

Yeah, when I first got my tablets I had to force myself to use the (and kept going back to the mouse, cussing all the way). It actually took a few weeks to get the hang of it, and then the mouse became more and more obviously clumsy in comparison.

It takes a little while - but once you get used to it, it's like drawing on a paper pad - no kidding!
