I still think that, if a page is not going to work well for portable devices (or for that matter disabled folks with screen readers, or people using text only browsers), it should degrade gracefully: if you're going to have a version better suited to those users, then it should be linked early in the page - not after you ask on the discussion page! 
 ::Additionally, the pages you refer me to aren't actually any better structured than the main page: but that is an issue I will take up there!
