I had a pair of MS optical wireless mice , one of them just does not seem to behave right (the one at work) so I am back to a corded mouse there (though still optical).

I really like the no fussing with hairy mouse balls.

However, a few people at work are heavy into action gaming (specifically Quake 3 and Urban Terror) and none of them have taken to the optical mice. Something about the motion not being right... they have all gone back to "old school" mice for the game.

Since I do not do a lot of that I really like the opticals.

EDIT: I see a reference above to infra red cordless mice, the one that I have is an MS mouse and it is not infrared. It does not have the be able to "see" the receiver to work. And that is nice since my desk is rather cluttered and the receiver is usually under some pieces of paper or the like.
