The lens on the frame and the swiping to operate it are pretty obvious to me in the demo video.

I think its going to be just as hated as google glass.

Does all that CCTV footage get firehosed to Zuck and friends so they can mass tag everyone in every photo whether you like it or not?

Exactly! Flying cars sound neat in scifi, but in reality they are fucking loud and require 10x as much fuel or energy to transport the same people or goods. Just imagine the constant screaming noise overhead and if you think people drive like idiots now, just wait till they have to drive in 3 dimensions. No thanks!
