The problem is the sheer emphasis on iPhone apps over seemingly everything else. We all would be better off (developers and consumers) if there was more discussion around cross-platform mobile development. I know there is some of this, but not at the enthusiasm level you see with App Store discussions.
No one should do anything they really don't want to do. That's not what I'm saying. (And more power to everyone developing for iPhone, whether successfully or not.)
What I'm saying is that in the long run, this is a temporary state of things, and I personally feel we are better to move beyond it sooner than later. Geo-social apps are a great example that will benefit from better cross-platform support. And doing it in-browser, or some other compatible way, encourages more innovation faster than having to develop for n different proprietary platforms.
