I'm one of the weird people who tried out the Google Glass. It was finnicky, 0 actual interaction with the modern world, lasted a good 45 minutes, melted your face, and had terrible audio.
But the thing is, if you could peak THROUGH the shortcomings, it was abundantly clear how an eyesight driven, glass form factor is the destination for computing. Smartphones were even less advanced at the time, but even then, we I tried for a few weeks making more extensive use of it, I would catch many glimpses of how "neat" this technology would be... even doing simple things like effortlessly capturing a picture on the spot, or videoconferencing with my gf (now wife!) showing her stuff in the grocery store and asking her what to get.
The AR capabilities, mixed with the essentially VR potential for movies/games, will totally be a thing and it'll totally live on our face as glasses. There can be details as to when exactly, price points ,etc., but the ubiquity of this sort of computing device will eclipse the iPhone when it comes time, and until then, slowly but surely change the nature of "working on a screen."
