As well as my previously mentioned Unicomp keyboard, I also decided to purchase a Logitech Trackman Wheel Optical. It’s basically a thumb-oriented trackball that resembles a standard mouse (with regards to clicking, scrolling, etc). Adjusting to using the trackball was extremely easy. I have one at work and one at home. I haven’t been able to use it for games yet, so I’ve still got a second mouse around for that (more on that in a bit…)
