My fiance recently bought me a Razer Deathadder, and while the mouse seems great, there are a number of issues with the difference in X and Y axis sensitivity, as well as diminished functionality of the two side buttons. Does anyone currently use a razer mouse on their mac? If so, do you use a program like USB Overdrive or Steermouse to compensate for the lack of drivers? .... or do you just game in Windows?
