Why are those the only choices? The Apple app store has a tremendous advantage from a mass consumer standpoint. If the Android platform is going to be anything more than a geek playground, it needs a professionally managed source of certified applications that consumers can be relatively certain to (a) work and (b) not turn their phones into bricks.
Such an option wouldn't have to mean that a middle east bazaar of unregulated uncertified applications couldn't exist as well.
But if I'm going to purchase, say, an accounting application I want to be sure that it calculates the sum of 2+2 to be 4. And I don't want to rely upon anonymous ratings from other users for that certainty.
This, of course, will cost $$$. Developers won't be able to market alpha versions of half-baked software as easily as they do now. And someone (the consumer) will have to pay for certification and testing. But that's the way the adult world of software development and marketing works.
