What happens when you want to listen to your iPod Nano on the can, but don't want to put on a pair of headphones for fear that you'll accidentally drag the Nano into the toilet? You use Green Power's speakers.
The GP 400N is nice since it slides back in while not in use, but you do have to charge it separately with a mini USB connection. You get twelve hours of playback on one charge. No real pricing info available yet. [GP-EL via Craziest Gadgets via Geeky Gadgets]
Update: Reader Dan found that they're shipping for $30 (+ shipping) and will come in blue, black, red and silver. Thanks Dan!
