What do you use for a mouse or trackball etc? What mouse do you recommend?

[Cleo]

Don't like cordless mice due to the batteries adding to the weight and also having to replace the batteries. Don't see the big deal of having a little wire connected too the computer.

This is the one that I've been using for he past five years or so.

I especially like that it scrolls sideways as well as up and down.
