I use the
Logitech Wireless Performance Mouse MX.
After trying to play Civ5 with the Apple Magic Mouse a couple of times, I decided it was time to get something else.... (the touch-scroll was messing up the zoom all the time!)
For gaming and some photoshoping, I'm quite happy with the Performance MX. Thee scroll is a little particular too so sometimes you just want to zoom a little bit and it zooms a lot.
Besides that, great all around wireless mouse!

Is there something you particularly like about the DeathAdder for gaming?
