Remember when Mark Zuckerberg blamed the problematic old Facebook mobile app--dubbed "freakishly slow" by some--on "betting too much on HTML 5?" So does backend-as-a-service (BAAS) provider Sencha, and to rebut Zuckerberg's assertion that using HTML5 was "one of [Facebook's] biggest mistakes," Sencha built its own mobile webapp, Fastbook, to demonstrate that HTML5 is ready for prime time.
Just about everybody agrees that mobile computing is the biggest thing happening in IT these days; it’s just that nobody can seem to agree about how best to go about it. Some developers swear by native applications that take advantage of every feature of the platform, while others argue for an HTML5 approach that sacrifices some of those features in the name of consistency and the ability to more easily support multiple mobile computing platforms. Others still, make the case for a hybrid approach that combines elements of both development strategies.
