While I agree that was actually good hardware
The best possible mouse wasn't a mouse. It was the Kensington expert mouse trackball. That thing is incredible. It's like the old centipede trackball. Rock solid.
I could twitch my thumb to have a slight press and make it fly across the screen and then catch it with my pinky while simultaneously clicking with my thumb as it traveled over the icon I wanted. Then I'd flick my pinky back and drop it exactly where it needed to be.
Years of mouse usage destroyed my ulnar tunnel. It's kind of like carpal tunnel but a different pathway. I could not use a mouse and found out that many people who use mouse hardware end up like me. But after 2 weeks of using the trackball, my arm stopped hurting and my productivity multiplied immensely.
I strongly suggest that all people try the Kensington expert mouse if they currently use a mouse.
