I have a black and cobalt mousepad from bigchalk.com. It was given away at an educator's conference which my father attended. My old mousepad had the Republican Elephant on it, but I had used it since 1996 so it was getting sort of worn out. Before that I had a plain black one from the computer store where we bought our first computer, a Macintosh LC.
I've had the bigchalk.com one since 2000, or when I got the iBook. I have two different mice that I use--one on the road that doesn't take as much power and one for at home. The road mouse is an orange USB mouse that looks like a hockey puck. It uses a ball and rollers. At home I have an optical mouse, mostly so I wouldn't have to keep packing my mouse up every time I wanted to go on the road. The mouse at home is an Apple ProMouse, which is a USB optical model. It's the black one, not the new white one.
My old Macintosh has a squarish ball and roller mouse. I still have the computer, too--it's got its original box and everything.
