It is strange to me that we should need a native client for performance reasons. There are numerous html5 games that have "native" feels. I understand the security concerns with exposing lower level access like OpenGl to the web and I understand why on browsers (both mobile and desktop) some hardware is not allowed to be accessed directly (and with good reason) but it is frustrating that performance is still the major driving force between native and web considering the obvious cross-platform-ness of web based approaches...
