I see people switching to iPhone from Android with some frequency, but I've never seen anyone go the other way _and like it_.
Really? In the past 6 months, I know about twelve people who have left their iPhones behind and went to an Android device, instead of upgrading to an iPhone 4 when their contracts were due. I realize this is anecdotal, but I see more people switching from iPhone to Android than the other way around.
