I'm not sure how the nexus one is doing, but before that the Droid was easily the fastest moving android device, and while its launch sales didn't rival the 3GS it was also US only and in a completely different landscape. That said it moved quite well and at the same price on contract (and I think off) as the 3GS. While the second part I think is probably true, with Droid users slightly less willing to make the small purchases, I don't think it has anything to do with affluence. Thats just the impression I've gotten from the numbers I've seen and my experience with people who own/want Droids vs. iPhones (actually about equal numbers in my circle).
