I also think we underestimate just how many apps are being created with the intention or desire of generating revenue that fail to do so.

It's a fairly arbitrary calculation anyways, the point is the expected value is on the same order of magnitude as that of a stable company man. The big question is what implications this new "career salary distribution" will have as it becomes more popular.

This 10000x. It is incredibly hard to compete today when there are 10 apps for every idea. Most of them suck - but it is damn near impossible to charge from day one and be successful unless you have a very large platform to advertise or are a prominent figure (something like Vesper from John Gruber). We're in it for the long haul with PaperBox (gopaperbox.com) - we intend to be the best app and continue to iterate for 3 years or so, and then figure out how to make money when we hopefully have a million or so users. Having said that, it is very hard to project out and keep growth going without a significant advertising budget.

This looks awesome, but then I saw there was no android support yet. Is there somewhere I can sign up for a notification once android is out?
