I've decided the only person who seems to think Flash and HTML 5 are mutually exclusive is Steve Jobs and his legions of users. There are things HTML 5 does better than Flash, and there are things Flash does better than HTML 5. (And for the record, video is one thing Flash does better.) I imagine in the future there will be blockers for certain onerous HTML 5 extensions, just like there are for Flash.

Flash is my bread and butter so you won't get any arguments from me about that.
I just meant that Adobe made the CS5 suite particularly unstable. Flash is the red-head stepchild of the suite. Lots of annoying bugs and crashes.

I do think HTML5 will replace a lot of the uses of Flash, like building entire rich-media websites inside the plugin and that won't be missed. HTML5 would allow much faster loading of those kinds of sites with lower bandwidth costs on both ends. Now where Flash excels is in places like DRM and dynamic bandwidth for video and for acting as a self-contained wrapper for scripted application.

I also think the fragmentation in HTML5 implementation between browsers will keep Flash going, too. With HTML5 you can't guarantee what a page will look like from browser to browser and that's not counting browser-specific extensions. Really, the move to HTML5 is moving us backward into the Bad Old Days of the 1990s where browsers had to be specifically targeted and woe be to the web designer expected to support a wide variety of targets. At least Flash allows a single, consistent target across platforms and browsers.

Yes... Internet. words.... You've completely lost me.

Uh, anyway, I guess I should clarify. I don't use Flash primarily for websites; I work on Flash-animated training simulations. html5 is sorta beside the point.
