I've immediately stopped using the mouse the moment I had the slightest cramping/pain in my hand, which was about 1994, when I started using a computer extensively. Never had any RSI otherwise, even when learning to type on a mechanical typewriter (ugh). > The Lumbricals are little muscles that enable you to keep your finger > straight > even as you bend the finger where it joins your palm.

While this was That's the first thing I did, as well. Now I have a 6DOF device on the left, which I still hope to put to good use one day simultaneously with the rodent.

I like them corded, since all wireless mice I've seen so far are too slow both on the link and on the sensor, the extra batteries makes the rodent heavy, and I don't like making it too easy for the government to track whatever I do that I do on the computer. Hence, I prefer my keyboards corded, too (as to timing SSH packets, I will soon get rid of that, too). I'm considering making a habit of switching of my mobile, too. (No, I'm not paranoid. My government is).
