I wanted to get a couple of opinions before I stated my experience. I like it OK, but I don't see much advantage over my Mouseman Optical in speed and accuracy. I thought the 2000 DPI would really be much more accurate, but I can't say that I noticed it.
Also, it is a little big for my fingers. At work, I have an MS Mouse w/ IntelliEye. This is the right-, left-hand specific predecessor of the current MS Intellimouse. I really like it, but all I can find are the newer, ambidextrous Intellimice.
