Is there an augmented reality aspect to these? I got the impression that there was not, that it was simply a little area in the corner of your field of vision where it would display things.
I believe that's what I heard as well. If I remember correctly, I think Robert Scoble said something to the effect of "It's like having a Nexus 7 in the corner of your vision." Apparently he's writing a book for Google Glass and has used them as part of the deal.
Well, there's a difference between holding-a-grad-degree level, and being a grad student. On the other hand if the implication was that undergrad degrees teach your relatively little in comparison to what they should, then yes.
