One of the best things about XMLHttpRequest is that it frees us from
having to transmit fully-formed HTML pages on each request, which is
great for limited bandwidth. The client asks for just the pieces it
needs.

On the other hand, the bulk of a page's content is often not markup or
textual data, but attached media. You don't need (or want)
XMLHttpRequest for that -- you can dynamically add DOM elements (or
tweak existing src attributes) as required for just-in-time media
delivery.
