> So they purposefully broke the spec (looks like compatibility WAS compromised, wasn't it) by having a USB connector but not allowing all USB ports to charge it. I'm fairly sure there is no requirement that your device is able to charge from every USB port. It is still 'in spec' because the cable is used to sync data. It only breaks spec when it knows that the hardware can take it (via apple drivers).
