Except that going across the street to CVS to get the exact same product at a better price is very different to switching from iPhone to Android. Apart from just the big outlay for new hardware, you have to figure out how to migrate from (e.g.) iCloud, what happens with your chats in iMessage with all your friends, the different way that Android actually works. Don't underestimate the degree to which small differences confuse non-techy users. Even just upgrading from one iPhone to another, or installing an iOS update, can be confusing.

No-ones going to do that to get slightly cheaper apps (if they are actually cheaper, which I doubt, because I don't believe that the Google App Store is actually competing with the Apple App Store).
