HTML5 will neither be as good or as bad as people expected to be, in my opinion. While it does present a uniform architecture for development and speed enhancements via access to hardware another more serious point is overlooked. The US's Internet infrastructure. we are seriously outdated. Until serious high quality high-speed penetration is achieved people well not put up with spotty coverage and slow connection speeds. HTML5 will only thrive right alongside native apps not instead of them, at least for the perceivable future.
