I've tried the MX Revolution and I'd recommend something different for you.
Even if your not a keen FPS gamer, I'd say get this:
Its a Razer Deathadder, retails at about £30 and is
the most comfortable mouse on the market, the top surface where the light is, is this sort of rubber material - and its the smoothest, nicest thing to touch, ever. And its tracking & accuracy match the build quality and comfort it has.
Definately worth putting up with a cable, the MX revolution is all plastic and cheap feeling, compared to the Razer.
Also, on the keyboard front - don't get ripped off and buy an expensive keyboard like the G15, I got one as a present and while being good, given the choice I wouldn't spend my own money on one. Get something cheaper that does the job, and spend the excess in the pub.
