If you started with the flat iOS UI from the beginning it would have been very difficult to get accustomed to. Nowadays, we don't rely on those skeuomorphic affordances because we assume touch interfaces are the defacto.
That said though, I do agree that we should think critically about seasoned vs beginner interfaces. We should strive to accommodate both without causing detriment to one group or another.
