I know I'm late in this thread but I have been following and looking into HTML5 since it's inception.
Couple of things, Apple is not being ignorant. Flash is a resource hog and the sooner it dies the better. Lots of people shouted when they stopped putting floppy drives on computer early, but guess what? Didn't need it, it was holding us back.
Flash only just got working on Android - too little too late and still resource intensive (Read battery intensive.)
So, scrap that nonsense already and move on...
Embedding h264 is just a case of tags, but if you want a proper player it gets into coding. Already though a couple of people have players in beta... it won't take long to pick up a good off the shelf solution.
Personally... I have been holding off more streaming content as I despise Flash.
The big reason Flash isn't dead already is purely down to advertising metrics that can be counted in Flash... HTML5 solutions will develop PDQ.
