That sucks that your usb port broke off like that. I have not heard of any others so your may be just crappy luck. I have always liked Mini Usb over Micro usb. I never understood why Micro became the way to go. It does soom a little to small to be strong. My Hero had mini and it just felt right. It didnt feel breakable.
Hey it could be worse. We could have a goofy iphone type of charging port designed to force you to buy $50 chargers. At least our cables can be bought on monoprice for .85c.
