I don't like the design. It's really ugly. But in principle, this technology could be discreetly put behind the rim of stylish glasses like you'd expect to find at a department store. The technology hasn't been miniaturized to that degree yet, and you'd still have to drive it with something but for non-AR applications it needn't be complex.

At $100 people would be willing to use this for various new applications. Education comes to mind as a particularly good application. Maybe sports commentary? Maybe pop-up AR booths in malls. That would be enough to jump-start an ecosystem, while the hard technical work is done.

We already have phones in our pockets. Allow me to stick a cable from my HMD into my phone and I’ll be perfectly content to carry the extra weight around. It just has to look decent at the ‘head-mounted’ part.

I'm an AR believer once you get like some nice 1st person Google Maps navigation etc in a small package. Until then it'll be clunky.
