Consider the Apple USB Cable:
Apple iPod / iPhone / iPad Connector - Proprietary circa 2000 design that was out of date before it was released. Pins typically fail within six to twelve months. Easy to knock out of alignment; occasionally hard to get positive lock. Internal parts made of plastic to avoid excessive wear with connected device. Reminiscent of recent Fisher-Price designs.
Blackberry Micro-B USB Connector - Industry standard that just works.
