Good to point this out... Flash works because the desktop platform has such a huge excess of computing resource relative to the needs of the applications built in Flash that some inefficiency in the name of an easier developer experience is no problem. On mobile phones, where you're almost always pushing the envelope in terms of available memory and CPU cycles if you want to do anything interesting, this suddenly becomes a huge problem.
