I requested a track ball at work, turns out, they had like 20 of them in some storage room that no one wanted to use. Shortly after I began using a track ball, others also wanted to try it out. Basically my entire department now uses trackballs at work lol
Trackball gang, how do you like trackballs for 3D CAD? Are there ones that can interpret three distinct axes of rotation or is everything just using two?
