Yes, and the OP is also using the term "Mobile First" differently than my own sense of it. To me, Mobile First means developing websites targeted at smartphone screens first, that scale gracefully upward to desktop size. The 320andup boilerplate is a good example [1]. I see it also means a more general business strategy of focusing on your mobile app first, be it native or HTML5, and then your website. But could be some mixed messaging due to the multiple meanings of that term. 1. http://stuffandnonsense.co.uk/projects/320andup/ http://stuffandnonsense.co.uk/projects/320andup/
