I agree. I like the iPhone. I use mine every day. But I've noticed this trend to make everything developed for it look and feel "like a real iPhone app" and not pay attention to other browsers. Why not develop for the web and make it look and feel like whatever it needs to look and feel like?
YC News, for instance, is very usable on the iPhone. Not surprisingly, Paul Graham's essays fit the screen perfectly. Neither seem to have been specifically designed for the iPhone, but bother work well because they are designed well.
