I did some research on mice, and I thought I'd pass it on. First, though, let me suggest that you get some of this stuff. Use it to paint a symbol on each of your wireless mice that matches a symbol on each of your mice dongles. It will help keep you sane. You'll still find yourself constantly in possession of mice and dongles that do not match, but at least they will have these pretty little symbols you drew all over them.
There is some interesting and exciting stuff going on with mice.
