I don't see the big deal. To me, the funtionality of the iPhone is nice, and one of the major reasons I would want it. It is no suprise, however, that the tasks the iPhone can do are not original. It can't really do anything new, and the big touchscreen isn't really new.
The attractive thing about the iPhone is apple's patented touch system, and that it is an apple product, so you know it will be of the highest quality, from a name we all trust and love. The funtionality and appearance aren't what is revolutionary or original about the iPhone, it's the all-inclusive product as a whole.
