I don't think Flash is at all threatened by the iPhone and iPad not supporting it.  The owners of those devices are a tiny but vocal minority who may never be able to use Flash on those devices, but that's the choice they make by buying a device they have artificial control over.  Flash itself is absolutely entrenched in the internet and unlikely to disappear because however many millions, out of a billion, can't use it.<p>You only have to browse down as far as the #2 website in the world, Facebook, to see a site that has extraordinary use for Flash and revenue and businesses built around it - Zynga is practically <i>printing</i> money.<p>Go down to #4 and you're at YouTube, who are going to be using Flash for the next decade while HTML5 trickles down to an audience that doesn't care and won't even notice when it stops being Flash.<p>Further down the list you see MySpace at #15, a site which has ties to musicians (generous use of the word) and many millions of users who embed their own or others' music on their profiles in .. Flash.<p>#29 is a live cam streaming porn site, unlikely to be replaced anytime soon by a non-Flash technology.<p>Flash isn't "just" video, it's a richer platform than HTML/CSS/JS, both now and next-generation versions, and it's used prominently by some of the most-trafficked sites on the net and less prominently by most of them.<p>HTML/CSS/JS is an <i>insanely</i> slow moving set of standards.  Everybody's holding their breath for HTML5 to "be everything they need" ... and it's going to do a lot and it will be, for a while.<p>But it's also going to be a standard for a very, very long time and technology isn't going to stand still just because the W3C can't keep up.
