USB Mice & Trackballs

While several grades of mice exist, there are a few pointers that apply to all mice. A mouse with a high sensitivity means you don't need to move your hand across the desk as much, and a high accuracy is vital for selecting pixels in Photoshop or getting that headshot in Unreal Tournament. The number of buttons on a mouse can reduce stress and improve reflexes by providing quick access to common functions like browsing back a page or meleeing an opponent in the middle of a reload. Most importantly, a mouse should be comfortable and ergonomic because you use it daily and most likely don't want to be one of the millions of Americans with Carpal Tunnel Syndrome.
