Re: Shot across the bow
The people saying there's no performance problem with Flash on budget Android devices (and I accept that the discussion is essentially my anecdote versus yours so there's no reason for a third party to believe any of us over the others) are missing the other significant part of my point against Flash — it's deprecated. As in, by Adobe. It will no longer be developed. One day soon it simply won't work.
I would therefore maintain that it simply isn't an option, regardless.
As for the allegations that Flash isn't on the iPhone because of greed, I strongly disagree. Flash didn't make it to Android until 2010 — three years after the iPhone's launch. That suggests it genuinely wasn't ready in 2007. I think it's more likely that Apple's initial decision was a technical one and that the subsequent fighting between the companies, from which I don't think Apple comes out looking all that good, caused it to entrench its position.
