I think this can be explained by general behaviors of people. People get things that they see their friends and celebrities using. Word of mouth and good marketing on Apple's part spread that device, which really didn't have any real competition. Then people stick with what they know. It certainly doesn't hurt Apple that the media loves them and are scared of Android. Not just tech media, but cites like CNN only mention Android when there's something bad about it. But they absolutely love the iPad. That stuff adds up. However, I've seen that people who generally will give Android a shot will be more likely to switch. Those that will actually compare the devices, sort of thing. As an example, my sister's BF was playing with his iPhone and couldn't do something. So I let him borrow my DX for a bit. After about 15-20 minutes, he was asking me what the device was called and where to get it. Just food for thought.
