I am considering getting one of these: <http://www.kensington.com/html/4136.html> simply because of the scroll ring even though I am not generally a big fan of trackballs.
It arrived today and I am using it right now (albeit it on a Windows system). So far so good. It's a bit sticky still since it's new out of the box, so accuracy isn't too good. I doubt it will stay like this for more than a few days though.
I am also determine to switch to left-handed mousing at the same time, so that's a bit of a challenge as well. We'll see.
Alex.
