This is fascinating. The Flash issue (or lack thereof) is a pretty contentious one, to say the least, and I've already discussed it here. I have long been an Apple person (before there were Mac people, really) but I find the Cupertino folks position on Flash very... well, very Microsoftish.

The iPad doesn't play Flash. Okay. Why not? Games use Flash. Web sites use Flash, especially galleries and the like. Apple is trying to reshape the web world and I don't see the gain from it. Because they want to promote their own version? Not really. Because they like HTML5? Could be. Maybe Steve Jobs secretly loves Silverlight, who knows.

All of this has little impact on clients whose web sites do not show up on their shiny new iPads. It's a very emotional reaction to suddenly be rendered invisible, particularly when your web site is an integral part of your business. And while you could rebuild with HTML, I wonder how hard it will be to wait and see how this plays out.
