They pose their models in such a way to hide it, but the temples of those glasses (where all the tech lives, presumably) are huge. Which feel like they'd both be distracting to wear and to look at someone else wearing. (Although this is certainly an improvement over the Google Glasses design.)

I would believe that some people would like a little heads-up display in their glasses. Not everyone. But some people. But I also would believe that the glasses would need to look almost identical to normal glasses for such a thing to take off. People don't want weird bulky shit strapped to their faces. Dark and moody photos that hide the actual size of the things won't be enough.
