I love flash and flash programming... for games, fun modules, interactive stuff. I do not love html5 and its lack of consistency and support but I do support it as much as I can. AS3 is great, and the core rendering engine is awesome (3d etc).
I have taught basics to master's classses in flash design and programming and I have always thought the cynical nature of apple to dismiss flash silly. there are iOS output modules specifically for flash, geared to have NO slow down.
then again beginners take the program, hack it, etc, and then get a job after 1 month of 10 15 minute youtube tutorials, even in fortune 500. this is no different than bad game programming and sloppy coding for memory and texturing (assets).
still, finding a way to truly stream H264 without flash or a php chucked fake out is something I really look forward to in modern interactive design. that, and legally having OTF or even TTF|PS font outlines in works.
