Food for thought: what do you think would happen if Apple opened up the app store to all devices (assuming there were a way to run these apps on Android, Blackberry, Windows Mobile, etc). Don't you think a significant number would jump ship to other phones (e.g. ones with replaceable batteries, slide out keyboards, removable memory cards)? It would be more beneficial to the other companies than to Apple in the sense that Android users, for example, would be able to choose from the Android Marketplace and the Apple app store.
