Mail is not a good example. Why would you like to read a collection of documents through A Single Page interface? Gmail was a fantastic improvement over Hotmail and Yahoo, and it provided UX innovations we still haven't caught up with, yes, but MPAs are naturally more suited for reading and composing them. Overriding perfectly clear HTML structure with javascript should be reserved for web experiences that are not documents: that is, videogames, editors, etc (Google *Maps* is a good example). The quality of the product usually depends on how it was implemented more than the underlying technology, but as I see it is: if it's a Document, if the solution has a clear paper-like analogue, HTML is usually the best way to code it, structure it, express it. Let a web page be a web page and let the user browse through it with a web browser. If it's not, well, alright, let's import OpenGL.
