Therefore,there's a need for webmasters quickly to adapt to this large audience and (re)write as needed with a focus on mobile devices.
That's the problem, the majority of Flash sites aren't owned or run by webmasters. We tend to forget at WebmasterWorld that we're the minority here where everyone knows how to build a site and the rest of the world needs help to do these things. Not only can't most of the owners of those Flash sites upgrade to HTML 5 on their own, the may not be able to afford to have their sites rebuilt unless someone has a frugal upgrade path.
Huge opportunity for some enterprising people that should get there sales pitch ready and start cold calling everyone with Flash sites and warn them of impending iDoom.
Sometimes because company has it's own new replacement, sometimes because they can't see the value in the future.
Even if they have an HTML 5 replacement for Flash coming, and I believe they do, after such a long and protracted battle about supporting the iPhone they finally won, said they'd do it, turned into a big fat lie.
Why should I, or anyone else for that matter, buy into their future plans?
Fool me once, shame on you. Fool me twice, shame on me.
FWIW, Now that Sprint has the iPhone, and I can upgrade for as little as $250, I was thinking of switching from Android to iPhone when Flash came out.
