It's not, and can't be. There's literally no implementation of DOM that can be fast. There's literally no conceivable implementation of the current Web that can do, for example, fast animation on a list of elements without horrible hacks (like cloning elements, taking them out of the layout, hiding the original elements and then animating the new elements).

And what point would that be in the context of "If OS vendors wanted web-apps to succeed, they could have done a lot more"?
