Forced Attrition

Me: Nathan, do you have the iPhone 4 or the 4S? Are you going to upgrade?
Nathan: I have the 4, I'm not interested in upgrading right now, my phone's fine.
Me: Really? There isn't that much of a difference? It's worth waiting for the 5?
Nathan: Well, it's not much of a difference for me. But as far as your phone goes, get a new one right now.
