I can only speak for today, tomorrow may be a different story. I think this will do well in non consumer segments like certain industries, healthcare, logistics, etc. But for your average mom and pop consumer it's going to have to shrink down a hell of a lot more, ignoring price for a second. Hell, look at 3d glasses, you can't even get people to wear those paper thin ones you get for free from the movie theater. I might wear these at a hotel or a plane, but not walking down the street, driving my car, or hanging out at the pub. I can't say I've experienced these in person so will withhold judgement, but I'm no stranger to VR/AR and have had several different ones and have gamed, attempted desktop functions, communicated, etc and at the end of the day it was just easier to use my computer and/or phone.
Miniaturize this into something the size of regular eyeglasses, or better yet contact lenses, price it reasonably, and it will start to make more sense for the mass market. Conversely when you first saw the iPod, iPhone, and iPad you instantly knew they were going to be a hit and haven't needed much evolution over their basic premise. I do think these will eventually be significant as the technology matures, after all consumers number one desire is to have a larger screen, but today it feels much more like a very clunky proof of concept.
