not the most full-featured peripheral in the world but who cares? it's twenty bucks and oh so useful.

has a tiny usb receiver that snaps into the bottom of the mouse when you're not using it. optical sensor tracks movement. compact enough to toss into your laptop bag but still feels good in the hand. plug-and-play on all the XP, 2000, and Mac machines i've tried it on. extended battery life (up to 3x that of other optical bluetooth mice, according to the website).

so what's not to love?

Brilliant shape, super confortable, very reliable!
