Lastly, trackball users can go to hell. Freaks.
I used to use a Microsoft Trackball Optical for gaming (I still use the trackball at work), and even though I was never big into online gaming, I never found it to inhibit my gaming. I could play FPS's just as well (if not better) with the trackball. It's nice to never have to pick up the mouse and reposition it. That said, I went back to mice again a few years back. But sometimes I wish somebody still made a decent gaming trackball. I've never liked Logitech's trackballs, and Microsoft doesn't make them anymore.
Oh, and if anybody uses those trackballs with the ball in the center of the trackball, I would call them freaks too. Trackballs with the ball on the side (for your thumb) are the only way to go. This comment was edited on Aug 13, 16:05.
