I'm not sure about that. Information on a single page with only a mouse or finger input is limited to only the things directly visible. Add in even one mechanical input system, say a keyboard, and the amount of information easily accessible from a single page increases dramatically The problem with modern web UI's and UI's in general is that they're optimized for a minimum amount of inputs at one time, usually one, that is directly accessible in a visible way. This I think, is what most people are actually complaining about when they complain about 'mobile centric ui's or touchscreen inputs. The greater the number of direct inputs available for any given single screen, the higher the information density and usability can be. Touchscreen and mouse centric designs ie. most modern web design, are designed with one, maybe two direct inputs, correlating only with things directly visible on the screen, at a time.
