They are serving a different market, and I've seen less demand since Android came out. I know at least a dozen people who have Android phones (that are quite happy with them) off the top of my head, and I can only think of two who own an iPhone. The Android people don't want iPhones, but the iPhone people look jealously at Androids.

This isn't a "techy" group either, it's mostly regular 20-somethings.
