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.
