Couple of years? With the speed the smartphone is going? Yeah...sure..
I recently upgraded to a new iPhone 4, and that will be doing me for AT LEAST two years, but probably double that. Its effectively replacing a phone I've had since 2005.
Not everybody has the luxury of keeping up to date with every advance in technology, and the iPhone has sufficient functionality to keep me very happy for many years. Its SMS experience (my major bugbear with my last phone) is far superior to my old phone, and it actually has a workable still and video camera. And thats not to mention a mobile internet experience that is actually useful (WAP was never that to me).
Sure, it will be considered "obsolete" in comparison to other mobile communication devices on the market before the end of the year, but the functionality upgrade across the board when compared to the phone it is replacing will allow me to be happy using it for many years (and considering its nearly $1300 price tag, I'd expect it to).
