One of my pet peeves with the current generation of mice is that the side buttons force you to move your thumb up, and thus closer to your index finger, if you want to press them. The best side button I ever used was on the Logitech Mouseman Dual Optical:

I never had to move my thumb far, and certainly never towards my index finger. Moving my thumb towards my finger while playing fps games throws off my aim so I tend not to use the side buttons at all.
I've looked pretty hard and I've never seen a design that's close to the Mouseman Optical in terms of side button position. Have any you by chance?
