Terrence O’Brien for Engadget:
We’ve caught glimpses of Mozilla’s smartphone offspring before, but Mobile World Congress 2013 was really the proper coming out party. Finally we’ve been given a chance to touch it, see it action and peek at the hardware it’ll be running on. Unfortunately, at this cotillion, Mozilla failed to make a good case for anyone to court its debutante.
Firefox OS continues to intrigue me in some ways, but overall, I’m getting the sense that O’Brien will be right here. Because, well, history.
