What are you guys talking about? If Apple went with a microUSB connector like every other phone manufacturer out there, they won't be able to charge you $$ for their proprietary cables and adaptors, and it would be easier for customers to switch to alternative phones later down the line without obsoleting their accessories.
Supposedly the new connector doesn't even pass analog audio/video like the old one did, so other than being able to connect it with any orientation, it has zero other advantage whatsoever. Well other than what is mentioned above. This is innovation people!
