There's been a ton of analysis of why it is Apple is doing so well in the middle of the rotten economy, but there's one bit I haven't seen anywhere: Unemployment is helping Apple. A lot.
Just among close friends, I know a couple people who have been laid off. When they go, they have to turn in their corporate-mandated Blackberry.
They have gotten used to having a smartphone, however, so they use a bit of their severance and go shopping for a new phone. They head to an Apple store. They may know full well that AT&T is a Big, Steaming Heap of Failure, but they also realize that if they are going to be unemployed, or turn into consultants, or whatever, that at least they don't want to hate their phone.
So, they get a phone that makes them smile. There's only one phone that does that.
I don't think that accounts for all of the 5.2 million iPhones Apple sold in the quarter, but I bet it was a lot of them.
