Two years ago, responsive was the near future (I remember this time very well, because I had been asked to lead the early design direction of a very large global website in the consumer electronic industry). The whole team made the decision to go responsive, and honestly we never regret it. Today, responsive is the emerging standard of design principle.
As a Design / UX manager it forces you to think in a new way (revise all you knew about screen layout and interaction model), and you learn a lot on Content and API framework.
Thanks to Brad Frost you don’t have to go the hard way. Check his excellent resource site, I wish I had it two years ago.
