Call me a "luddite", but I don't like it!
I particularly don't like the idea of walking around and being able to have information 'transmitted' to my eye-balls about people I see walking passed me, as demonstrated in the vid. That could have all sorts of nefarious purposes, particularly when coupled with various other rfid technology.
I notice they mention the blood-glucose application, which might be one way to win people over.
If they're capable of doing this though, think of all the other illnesses and conditions that could be combatted overnight.
Doubt that'll happen though.
