I saw this yesterday and today and immediately thought of you and Metawatch. I haven't yet read about it in detail, work keeps getting in the way, but I have to fall back on my previous thoughts on it.
If this will be a connected display for a smartphone or tablet, an accessory, then it will be amazing. Everything we've seen thus far points to the possibility of Google making the glasses the device, however, and I just can't see anyone paying four to five hundred dollars for a fourth screen (TVs don't count anymore) with such a limited application. Would you be wearing them while on the computer/tablet/phone? Of course not, that's what you're on the computer/tablet/phone for.
Google should take a look at what you're doing, though I think I would prefer your version in the end.
