Because of a struggle with "normal" mice, me and my wife use for a long time the Logitech Marble track ball (Two generations, because of the warranty of teh stuff!) Since then we did not have any RSI complaints.

BTW. We use Debian Sarge....

Just today I bouht a new mouse for my mother for her MSN webcam install. Windooz all on the box.

Just wanted to try the Debian Sarge hardware recognition, I plugged it in.

What a supprise!! It did work and even the scrolls did work. Or even. It is not a "scroll", it is more like a thender glymph...

Besides that, the pad at the laptop works togther with this mouse!
