I *hate* the Mighty Mouse, but I've tried a couple of others and I notice they don't seem to play well with Mac. So does anyone have any recommendations for the best mice that play well with Mac? Also, I love trackballs, but I've only ever used the thumb trackballs. A.) is it easy enough to transition to a regular trackball and b.) which are the best ones for Mac? Any and all advice would be greatly appreciated.
