>>>"Mice don't ride on the ball, they ride on small pads on the mouse's underside. Thus, the boing mouse, or any mouse, with or without a ball, move smoothly on their pad."<<< Don: My mother-in-law likes to start arguments for the their own sake, too 🙂 Yeah, a mechanical mouse rides on pads, but that's to allow the ball to roll _in contact_ with the pad and the mechanical sensors inside the mouse. That is _friction_ at both the top and bottom of the mouse ball, and it is that friction that, by the very nature of the term FRICTION, causes the mechanical mouse to be jerky (the more dust/dirt that collects on/around the ball, the jerkier the movement is).
