I'm going to go out on a limb here and predict that this whole native app market is going to implode in the next few years. Even the "high quality" iOS app store is stuffed to the gills with junk apps now and the majority of the few apps that are making real money are trading on gimmicks that are bound to exhaust their novelty soon enough.

I'm actually rooting for Windows phone though because if it gains any real traction and people have to start maintaining three separate code bases for every app the balance is going to tip decisively to the mobile web.
