Do Most Mobile Devices Actually Support HTML5?
With all the talk about HTML5, one would assume that every mobile device on the market must support it. The reality is that although the industry is pushing for its acceptance, most mobile devices still don't offer much in the way of support for the emerging standard.
In a study by Netbiscuits, thousands of different devices that accessed mobile web data on its servers were analyzed to see how many HTML5 features were supported. Unfortunately, they found that there weren't that many devices with HTML5 support at all.
