A4 Tech's NB-30 BattryFREE wireless optical mouse
We're not entirely sure why they chose to purposefully misspell their product's name, but A4 Tech's NB-30 BattryFREE wireless optical mouse cruises around on a special USB mousepad (which they claim is RFID-enabled, oddly enough), which more than likely provides power via the principle of inductive electricity (the same kind of thing that recharges your Sonicare toothbrush without contacts). We don't know for sure though, and they're probably not going to tell us, but either way it's still not going to pry loose from our fingers a good ol' fashioned Bluetooth mouse.
