Actually, I really like this guy's idea, which is to make HTML5 a publishing target from Flash.
Screw HTML5 - how much longer are we going to be playing with this legacy 90's garbage?
The only way to ditch this legacy rubbish is to move towards VM-based platforms. It's already happening in the hardware world. Flash/Flex and Silverlight are the Internet-RIA equivalent of the same trend. Stop trying to salvage technology conceived decades ago. What a waste of money and time!
I'd rather see Adobe team up with someone like Microsoft to engineer a next generation browser platform than play nice with Steve Jobs and his kool aid drinking customer base (who seem to be tasting poison more and more lately). Stop trying to build applications within technology that was designed to display static text, and start building applications on technology designed to run applications.
