This has nothing to do with not being "rich enough." Most Android smartphones are just as expensive as the iPhone. Many people here in Europe or Germany at least get their new phones with a 2 year contract. The big difference here is that people don't rely on iMessage, so you're not stuck on just using iPhone.

Most people I know and see on trains/buses are using the latest Samsung Galaxy S devices and like the design and all the features the device has to offer.
