With Microsoft now on board with the try to use html 5 and not plug ins its just a matter of time when flash is not needed at all.
LOL.
Only someone with very, very, very limited knowledge on the subject would argue that HTML5 can compete (or come remotely close) in "3D gaming" with Flash.
But there are so many here with just such limited knowledge....
HTML5 has its purpose, as does Flash. They will both coexist for the foreseeable future.
Apple is making a purely business decision to ban Flash from iOS, then spinning it into some mystical technical mumbo-jumbo.
Which then gets repeated ad nauseam by those Apple fans possessing the very, very, very limited knowledge I mentioned above.
