>Why can't you have only one version, and someone on mobile will zoom in and out? Because to do that manually is usually clunky. Responsiveness makes it happen automatically and thus smooth. >A web site version with 10 things on the header is going to piss people off on the mobile app regardless of how responsively those 10 things show up in their face. Good responsive sites rearrange those 10 things in the header so that they are not "in your face" as you say. See also: Twitter Bootstrap.
