I am wary of demos of unfinished products. By the time these products hit the market, the scope is considerably reduced and they end up being a ..meh :( I hope Google Glass isn’t one of them, but comparing yesterday’s and the last year’s videos tell kind of the same story. For most part, it still looks like a wearble camera (Go Pro-ve me wrong!). If the voice UI works well, that would be game-changer.
Next year: Google buys Go Pro and launches Glass Pro?
