Stevet - the problem is that the USB was never intended to be used for high-power devices like hard drives or for recharging equipment. The USB spec says that the port must provide only 500 mA of power. Many computers provide more than that, which is why you can buy those little portable HDs now, but not including an AC charger with the PRS-600 was still a really bad decision on Sony's part.
