I get a bit exasperated reading all the HTML5 boosters who, for understandable political reasons, blithely dismiss flash at a technical and especially domain-specific level. Flash let's me do the following in a browser with relatively clean deployment, like, two years ago: http://www.icecreambreakfast.com/flash3d.html . I'll be ecstatic when I can reliably get the same possibilities from HTML5, but these are real, hard-and-fast features based on specific knowledge about a relatively complicated domain, and often times I get the sense that the domain knowledge issues and feature specificity are somehow beside the point with Flash bashers. At least for browser based games, Flash lets me do a lot of things I want to do right now.
It's hard to shake the feeling that a lot of the anti-flash feelings mirror the structure of GIMP versus Photoshop as discussed occasionally on slashdot. I love the idea of GIMP, politically, but taking away Photoshop from me would literally be like partially lobotomizing me.
