Assuming a new AW comes out every year like the iPhone, which is a big assumption as I can't envision what other features can be put in the AW after Apple comes out with a cellular AW. Anyway, I can't see myself buying a new SS AW every year . . . too expensive. But I can myself buying the aluminum AW every year. I definitely prefer the SS though. If there's a new AW this year I don't know if I'll skip the upgrade and wait until the next one or get the aluminum version or really splurge and get another SS. I had the SS AW0, but I felt AW2 was a big improvement so I went ahead and got the SS AW2 with no regrets.
