Hey Peter: have you ever tried a large trackball?

20 years ago I had a coworker who used a Kensington expert metals and I laughed at him. He said he was mesphobic.

A couple of years later I realize that the intense pain in my wrist was because of how I used a mouse and there's nothing I could do about it. My forearm to my pinky was f*****. And then I try to Kensington expert mouse which relieve my pain and allowed my ability to focus the pointer to be much much better as compared to a mouse, at least for me.

There was a training time. when something is on the other side of the screen with a mouse your arm and your wrist actually have to go move and push stuff. When you deal with the track ball you hit it. You tap it and let it spin in the direction where you want it to go and then you grab it at the moment right before it gets near it so you could focus closely. It is so much different from a mouse that there is no initial comparison but you might find that this particular method of interacting with the computer is better than a mouse. Problem is it takes a month or so before you cross the threshold.
