<SNIP> Also if the iPhone 5 will have an A5 processor it will be a lot more powerful than most other phones (a LOT more powerful than N9!).
Also I think that the form of the N9 matches iPhone rather closely (most closely matching Nokia phone in any case. Don't get me wrong, N9 has a lot of original features, but for most people the choice between N9 and iPhone 5 would be no-brainer: iPhone, especially if similarly priced.
