Yes, all of what you said is needed. I would also wonder what it weighs and the weight distribution. It would make more sense if it was for work first (they can pay for the improved efficiency) then the gamers (they want to pay to play (and show off). Then it might come to consumers (in a much more streamlined form). With all the bad mouth Glass got for ugly (looked cool to me but I am a nerd), it will have a tough row to hoe in consumer land.
Still, as a user, I would like DIY guides, tour Guides, road info on HUD, and instant Internet look up (no digging out the phone/tablet) as a start. Better have ear buds so it can noise cancel.
Does it have a phone or is it Wifi only? Does/can it store the continuous video or process and toss? Can it precisely overlay objects (put a new face on some one)? Can it augment the view(telescopic/microscopic vision)? How does the eye focus on near or far items compared to real and VR?
