I disagree - the controls are awful. And it's not even a great technical achievement - they got the worlds of Liberty City and Vice City running on a portable years before iOS in the form of the PSP games, and with much better controls. The wow factor is somewhat lost on iOS.
The much better controls coming from the fact its got physical buttons and a stick?
For a pure touch screen based experience I don't think they could have done much better
