mouse or trackball (Score 1)

I've been using a Logitech Marble Mouse for 7 or more years and I love it. The name is a misnomer in that the trackball is much larger than a marble. They run between $10 to $20 dollars. People have made fun of me for using a track ball, but it works great with my laptop sitting on the couch. Just set it next to me and it never has to move. I use it a lot for digital photography editing and iMovie editing.
