Here's the problem with tiny "personal computers" like the iPhone. They are only for consuming content, not for creating it. Basically, it is like watching TV, except in text form.
There's nothing wrong with that, but people use their computers for more than just mindless content consumption. Even the "average joe" probably plays a 3D game from time to time, or send emails to his family, or whatever. Anything like that is painfully impossible on such a small device (at this time anyway).
So while the iPhone is great for looking up someone's phone number on Facebook and then sending them a "hey lets get coffee" text message, it's not so great for anything more complicated than that. And even the most casual computer users need to do things more complicated than that. (This post would never have been written from a phone. The same goes for delicious bookmarks, and everything else Web 2.0.)
