The more I read about trackballs, the more I get the feeling that none of the current models are any good. It seems you have to find existing old stock to get a decent model. Are you using the thumb-ball or finger-ball type?
The idea of using a trackpad to make gestures sounds interesting, but I've never tried it. Some of the new Microsoft mice apparently work with gestures as well. Anyone tried them?
