My mouse is by far the most used computer accessory I have. Having a good one is important for someone who spends as much time as me in front of the computer. I have been using the Revolution for about 4 years now and have yet to find its equal even in the newer models coming out this year. Its elegance and durability make it a no brainer for any heavy computer user. Watch the video and find out how I configured my buttons for maximum efficiency. This mouse also works well on the mac.
