Well, PDFs are yet another issue. It's preformatted documents made specifically for a certain size paper. This is not optimal for documents to be read on screen/mobile devices since they handle zooming, changing text sizes etc poorly. In a way I can agree with you that application delivery would allow document distribution as well, but I think the benefits of a unified standard for this that focuses on content rather than presentation is a key feature of the web that we should not loose.
