Wow! Mouse users make me laugh. Precision, speed, just flip the mouse pad. LOL. I use a trackball, Logitech Mouseman marble for everything and at all times it is fast and precise with no flipping. Primarily a FPS gamer, and my 20 dollar trackball has, over the years, led me to victory over far more costly equipment. My competitors think I'm lying when I tell what input I use. I started with mice like the rest of you, but was introduced to a trackball in Drafting, and have never gone back. Mousing is very inefficient, lost of wasted movements, wasted movement equates to lost time, I can do with one fingertip what it takes half a hand to do on a mouse.
Viva Trackballs! We don't need no stinking mousepad, Vamanos!
