yippy said:But you know you can buy rechargeable AA batteries don't you? I have a couple sets for my camera and use rechargeable AAA for my Radtech bluetooth mouse.
Sorry if this sounds snobbish but I find that a little antiquated though, don't you? Most portable technology these days is rechargeable... Phones, laptops, iPods... Why should mice be any different? I'd have to buy a recharger and remember to take it with me wherever I go. Why can't I just pull a cable out of my bag and plug one end into my mouse, the other end into a USB/Firewire port and charge the thing? Makes more sense to me.
Edit, no iPod takes advantage of firewire 800. In fact, the latest models of iPods are USB only, no firewire transfer supported.
So there we have it folks, proof positive that USB charges
