A lot of people have more than one monitor, so it can often be more efficient to use a separate mouse for each screen. How many mouses do you use and how?
I have been using 2 screens at home and 4 at work for many years now and I have no idea how I would use more than one mouse in either situation. I simply move the cursor across the screens as if they were one very wide screen. Am I missing something here?
I've often found that due to decreased precision available using my feet, a trackball is often easier. Is this a common thing or do other people find that their feet are prehensile enough to allow proper manipulation of a traditional mouse?
Have you tried sitting on your mouse, and controlling it with your butt? Like yourself, I had precision woes when using my feet. Instead of upgrading hardware, I just put the mouse on my chair. The mouse can't be kicked away, and I can control it just fine with an appropriate wiggle.
