[Dysprosium]

I don't see how pages transition is trying to emulate native apps. It still falls under the paradigm of accessing a resource at a given URI, which is what the web is. Personalizing the way the resource is loaded by the client and displayed to the user? That's just cosmetics we should definitely care about.

Currently, the most popular way of implementing "native apps" in the browser are Single Page Applications, which breaks the web paradigm and hence have practical drawbacks such as the inability to open some resources in a new tab or to bookmark them. One motivation of SPA is the fact that loading a new webpage produces a blank intermediate screen during downloading, which is lame, especially for pages which are almost the same. Pages transition can change that, and in a beautiful way.
