I fly a lot for work and enjoy my iPod Touch, but find it runs low on power after a few hours of watching video. I originally learned of the accessory power device for iPods from an ad for the Richard Solo unit - a fancy $50 device made of brushed steel with a built-in laser pointer or something. The problem with that, though, is when it is attached to the Touch it blocks the headphone port - there is no cable as it is apparently designed to add a couple of inches of length to the unit (it was really made for the iPhone, where I presume one would be holding the phone next to one's face or using a Bluetooth earpiece).
