you'll have to try really hard to sell me on wireless. i don't like a super light mouse but the wireless ones i've felt are just too damn heavy, and in the past i've experienced input lag among other input problems, plus i'm not inconvenienced by a wire so i just don't see the point in putting up with all that.

and @devour...last optical i had was a logitech mx310, which was probably the best overall mouse i ever owned. however my brother's had issues, and the optical i had before that did this weird thing where it'd look straight up and spin in circles for a few seconds if i tried to turn too fast in cs or CoD. i actually got a steam account banned for a few weeks because of it, until i appealed. loving laser though.
