I've got a iPod speaker shelf I got from Pottery Barn. (Clearance 20 bucks, woohoo). I usually use it for when I soak in the tub. Tonight, Gameboy came out of his room with his Nano and asked if we'd hook it up for him.
His needed to be charged, but the better part of his library is on my iPod. So we hooked mine up to the speakers. He's been in he tub for almost an hour, humming along with the Star Wars Trilogy soundtrack.
John Williams is the man, indeed. He keeps my kid in the tub!
