They did the concept video http://www.youtube.com/watch?v=9c6W4CCU9M4 I guess that's the long term goal. I haven't seen any real-world previews yet. I guess that's what is most exciting about the hardware going to developers soon, we should see some images.
Re-watching the promo video, I'm surprised at how basic it seems. For example, when the user had picked up the book about ukeleles, I was expecting a bunch of comparable price listings to pop-up, or at least the book's ISBD info.
And face recognition is an obvious use, but I think people would've freaked out if the promo showed how you could look at people and ascertain their identity.
