Mmm. Charge off USB. They don't mention a charge time, and at 500mA maximum current draw over USB it'll take hours when fully switched off... (unless they're ignoring the specs, which would cause incompatibilities with correctly designed motherboards). It's only USB1.1, too.

Firewire has a far higher current limit, hence the iPod can get away with it (even though it takes several hours to recharge too).

It's also far too big to be considered an iPod competitor in my eyes - the iPod is about as big as my jeans pocket can manage!
