I have a 12" usb extension that is very flexible.
I have it plugged into the usb host and there is not any strain at all on the usb port.
I would much rather carry a cable than take a chance on damaging the unit.
Also, from what I see, the only thing holding the usb port in place is the fact that it is connected to the pcb.
So how would a full sized port would withstand any more stress than the mini port?
