One thing worth noting is that your comments on the pricing are generally rather US-centric; the US telecoms market is very different from those in most of the rest of the world. In most European countries, for instance, iPhones are available on all networks, and at pricing comparable to high-end Android devices for the iPhone 4, or mid-range Android devices for the 3GS. It is much-rumoured that Apple will eventually also compete in the low-end smartphone space; a sort of equivalent on an iPod Nano.
