Thank you all for your responses.
I had read the page referenced. It is interesting.
However, in this day and age it is difficult to trust one statement. I do my best to learn to trust people, but I don't know Graphene. Of all the organizations in the world, Google is one of the most untrustworthy of all, and anything they say or promote is questionable at best. It is hard to tell an apologist for Google from some disinterested third party.
