Gamepyre.com takes a look at the Logitech Revolution Mouse

Logitech bills the MX Revolution as the world's most advanced mouse. To a certain extent it is evolutionary. From a gamers' point of view, you would be better served by a G7 mouse, as the resolution of this mouse in actual play is not good enough to play the latest and greatest FPS games. Regular mouse users will love the new features including the quick-flip through documents and the Search button. As a gamer playing through games like Rainbow Six Las Vegas and STALKER this mouse doesn't cut it and it is for those reasons I give this mouse a Silver award instead of a Gold Award. The other factor is the price. The price for the MX Revolution is $99, which is as expensive as many wireless keyboard+mouse combos in that same price range. In the end this mouse costs too much for too little and is better geared for a consumer product than a gaming one.
