Based on the results of three 2009 surveys, Forrester says HTML5 won’t replace browser plug-ins in the short term. In a report titled, “Does HTML5 Herald the End of RIA Plug-ins? Not really,” the company’s analysts assert, “For at least the next five years, the answer is a definite ‘no’; inconsistent implementations of the draft HTML5 specification and immature tooling make building HTML5 apps that work with consistently across browsers and operating systems a real challenge.”
Forrester adds, “Ultimately, HTML5 and RIA platforms will be complementary technologies and enterprise development shops will need to invest in both approaches to deliver expressive applications that combine reach and richness.”
