I guess I struggled a bit with Utopia because it is in the context of a pdf which just seems completely the wrong direction to me. Seems to me that display isn't a problem really, the web can do it all already, and I didn't really understand why they didn't expose all of that information more on the html version. For me it's the authoring side that needs the work. On the other hand the continued preference for PDF does seem to be pushing things in the direction of laid out content. See under iPads and magazines for instance.
