Whenever I try to use a touchpad, my mouse is prone to jumping around like a caffienated kangaroo on steroids. My problem is, of course, that the sensitivity is too high- but I don't like to have to push on the touchpad, I prefer to touch the touchpad. Pushing on it makes my tendonitis flare up.
But damn it, why did they have to get rid of laptop trackballs? A trackball, right where the touchpad is, is so much easier for me to use. Why did they have to give it up?
The best laptop trackball I ever used was on a really old Texas Instruments computer running OS/2 back when I was in 4th grade. I took it to school and typed everything I was expected to write, even for the teacher who didn't like that idea (the principal forced the issue), because my handwriting was rotten enough it got classified as a learning disability. (This was a reasonable classification.) I had physical therapy to improve it; it helped only moderately. My handwriting is still poor, although at least I can read it now. Anyway, that trackball attached to a special port on the side of the computer; it then remained just to the right of the keyboard, sticking up at about a 30 degree angle. The left mouse button was actually the top button, just above the right button, and it was easily reached by index and middle fingers with the thumb on top operating the ball itself. It was probably the most convinient mouselike input device I've ever used on a computer. Why don't they make them like that anymore?
