How does the long tail of App Store look? More to the point how does the backlog of apps not yet tester and approved look? What is the cost on average to develop an iPhone app? How many developers have made a profit om their apps? You see where I am heading. Is the AppStore a huge success for a few or is it alright for most developers?

Alot of questions. Important ones though. Help me out here and share what you know. I will share everything I find out.
