Mighty Mouse

When I first started messing with cordless mice, I had a run in with a unit that ate batteries at a prolific rate. I wish I had found this model instead. The NB30 from A4 Tech eliminates the batteries altogether. The mouse draws power inductively from the mouse pad, which in turn plugs into a USB port. The pad also replaces the usual dongle used by wireless mice. All for only $39! Now is someone would only come up with a laptop where the mouse dongle was built in...
