erm, you know that battery tech hasn't changed much in the last 20 something years right? With USB 3.0 supporting 1 amp devices, I think we'll be seeing more power hungry usb devices than ones that can run on a battery pack. Bluetooth was engineered for the "USB" of mobile devices... I don't think there's a single battery powered platform that makes heavy use of usb for these obvious reasons.
