Gamers are always looking for the edge over their competition. Whether it's hardware or software, strategy or unplugging your opponent's machine, if it helps rack up the frags, it's a good thing. One of the most important weapons in a gamer's arsenal is their controller. If you're using a junky clunky five year old PS/2 or ADB mouse and think it's fine, you're dead wrong.

In our search for the best tool for the job, we came upon Kensington's TurboBall. We plugged this USB packing slug-shaped trackball into both a PC and Mac to see how it fared, both in gaming and normal use. Here's what we think.

The TurboBall has an excellent layout. Your hand lays on the desk next to the TurboBall with your index and middle fingers controlling the ball and your ring finger sometimes joining in as well. Two large buttons are in easy reach of your thumb and your ring finger and pinky each have their own equally large buttons too. In the center of the TurboBall is a wheel/button that is in easy reach of several fingers and your palm.

The TurboBall is quite comfortable to use. It sports a large ball, which makes fine adjustments of cursor position easy and, at least for me, is the most comfortable kind of ball. Also, Kensington uses by far the smoothest trackball rollers in the industry. The well-placed buttons click firmly yet move easily and have a solidity that promises years of service. Our only serious gripe about the TurboBall's ergonomics is, the buttons click too readily. So if you're like me and push buttons like an astronaut monkey, it's easy to accidentally hit the wrong button.
