Personally, I switched to a trackball years ago, and never looked back. I have to use a mouse at work, and I feel handicapped by it. Trackballs are awesome for graphics stuff and for gaming. As long as you have the mouse speed at a reasonable level, trackballs allow very quiick, accurate movements, which is very useful for any kind of gaming. I've seen some people use trackballs with low mouse speed, which sucks... you should be able to get the cursor anywhere on the screen without lifting your hand.

I used Kensington trackballs for a few years, and I liked their trackballs when new, but they had poor durability... I went through two trackballs in three years. One thing I didn't care for was the button positioning, it was always awkward to right-click for me. My last Kensington was an Expert Mouse Pro, and it had mediocre response, the extra buttons weren't all that customizable, and the scroll wheel was not in an easy-to-reach place.

My current trackball is the Microsoft Trackball Explorer, which is great once you get used to thumbing for the right-click. I've had it almost a year, and I'd have to say it's the best trackball I've used.

The thing I keep meaning to get is a graphics tablet... no good for gaming obviously, but I'll bet they're awesome for graphics once you get used to it.
