Curious...I could provide pic examples but I think you'll know what I mean when I say that the USB cable provided with the TP, plus the socket on the bottom of the unit are a curious "beveled" shape that seem to only be on the HTC Touch Pro. The car mini-USB charger I got, plus the BT unit I have, both have a kind of symmetrical accordion-"crimped" mini-USB plug and socket, and I assume that design is much more common.
Matter of fact I was scared that somehow HTC had made a proprietary design so that none of the other chargers would work with it--happily that's not the case and the Motorola car charger I ordered fits and works fine.
But why would HTC do this for their mini-USB plug design? Just to scare us?
