Man what a great mouse! I was skeptical at first but now I don't ever want to go back to a standard mouse again (except for gaming). It's nice that the mouse itself doesn't move. It's especially convenient when I'm laying on the sofa or in bed and surfing the internet on my laptop. Anyone else ever try one of these? http://www.logitech.com/en-us/product/wireless-trackball-m570
I can't use them - just too foreign. We sold them where I used to work though, and they definately have a devoted fan cub. Some people won't use anything else.
It did take me a few days to get used to using my thumb instead of my hand/arm to scroll around, to the point that at first I almost returned it. So glad I didn't.
They say "once you go thumb, you never go back"... or something... But I actually have gone back... either one is fine. I reckon you'd wear out your thumb after a while though... end up with arthritic thumb....
Switched to the trackball 12 years ago, I love it. I've got the one with buttons on each side of the track ball so I can switch to left handed when I'm watching porn.
