Please no. IMO this makes most pages unusable on mobile. Most websites, e.g. news websites with long-form articles, shouldn't be using mobile pages / responsive design / zoomed-in layout at all. Web apps (Twitter, GMail), maybe. But most mobile pages are <i>far</i> more unusable than desktop versions (looking at you, Facebook and Reddit).
