True that. I got a VX Revolution (small wireless notebook mouse) about 4 years ago and the thing is still going strong. I've only changed the batteries maybe twice while using it at least 6 hours a week. I used to keep it in my book bag and take it and my laptop to classes. The VX doesn't have a scratch on it after 2+ years of getting thrown around my back pack, while my laptop is no longer usable...
