Nearly six years ago, I wrote an article lambasting the smartphone industry for still trying to make folding phones happen, after years of trying and failing. It’s a gimmicky form factor, I proclaimed—bulky, fragile, and destined to go the way of the 3D TV, which was another example of manufacturers trying to push something for which there was no appreciable consumer pull.
Then, of course, Samsung and other manufacturers went on to make something of a success of the folding phone. But how wrong was I, exactly?
