I despise "responsive design". For years, web sites worked great on my iPhone, iPad and laptop. More and more often, I'm getting web sites that are nearly unusable on my iPhone as they become "responsive".

While I appreciate making bigger touch targets and lighter-weight images, I really like being able to scroll around horizontally and vertically, zoom in on stuff I want to see details of, zoom out and get an overview, etc., and as soon as you make your design responsive, I lose that.
