You can never have a true Coke vs. Pepsi competition for the android and iphone because Iphone is proprietary and adndroid is open source. If Apple tries to compete directly with android they will lose out eventually because the nature of being open source is infintely more flexable than being proprietary.
I think it would be kind of cool to see Verizon spurn Apple and go with Android phones, just to get a Coke vs. Pepsi competition going.
