40 Hour iPod

Good post on BoingBoing about this:

Run your iPod for 40 hours
This external iPod battery provides 40 hours of playtime and includes a USB port for plugging in USB-charged devices like PDAs and cellphones. It's $100, and no indication of what it weighs.

Also, if you have one of the voice recorders for the iPod, this means that you could potentially now record 40 hours of everything you hear without a recharge. I recorded a whole hour one time just to see how it handled longer bits of audio (and I could hear every bit of dialogue from that episode of the O.C.; still have it on my iPod actually. The O.C. is a good show.)
