html5 really isn't the panacea that it's being made out to be at the current time. It's two years from draft stage, in isn't scheduled to be finished until 2022. In the current scheme of things, flash is still much better than html5 in many applications, and by this I mean less processor intensive when doing the same jobs.
All rhetoric out of Cupertino aside, you still need to support Flash right now to really have full featured web access. Yeah, the future will support more stuff, etc, but right now, there is a lot that you can't do on your iPad or iPhone because of lack of Flash support. And Apple sounding off about closed and proprietary standards is pretty ****ed disingenuous when you look at the way they do things.
