I am going to vent. Hopefully it will not do you harm.
The trackball (at LEAST if you get a good one) is better.
Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better. Better.
Get one!
My favorite expensive one is MouseTrak professional. My favorite cheap one is Logitech P/N 804377. You cannot get a trackball in a store, let alone a good one, they are so unpopular. You have to do it online.
