I'm not sure the new connector is entirely Apples fault. As a company Apple is all about pushing the boundaries and moving forwards. Sure it might alienate some and frustrate others, but they do appear to have a clear roadmap for their devices; it just might not make sense to us right now.
But the change in connector was always on the cards as technology never stays the same for too long. Car kits etc. will no doubt evolve for compatabilty, but the way the iPhone connects and talks to your car might also be changing? Moving away from wires and consoles and cradles and connectors...music over Bluetooth anyone?
I just feel that the whole 'OMFG they changed the connector' reaction is a little OTT.
