I can see major benefits from a learning point of view, and admit to wishing for the source code of some apps on my own phone for this purpose. There are only so many HelloWorld tutorials I can read/implement (in other languages, non-mobile), before getting bored of doing tiny, completely unrealistic things with code. Seeing how a larger codebase, particularly one that I've been using as an app for some time, is structured and hangs off device services (lbs, vibration, or even just graphics) is of huge interest to me
