I love to get a set of these; 1280 x 720 with a 40 degree field-of-view, per eye - in what looks to be a lightweight "glasses-style" frame. That's way better than most other models (like Vusix) - though I know of a couple of other companies that make better displays (though well beyond even a pro-sumer price range).
All in all, these are devices looking for a market; when the Vusix and similar came out, I was hoping I would soon see them at Fry's Electronics, but I have yet to. These displays will probably be the same way. Ultimately, they are a niche product, and probably suffer from the same issues that any display that forces your eye to a fixed focal plane do, which is mainly eye strain and fatigue.
Which is really unfortunate - the possibilities for gaming alone are amazing (when, oh when will I get my home VR deck to play Dactyl Nightmare again)...
