All of these are great so far, but the ones that hover out in front of you need to have a some sort of privacy option. Maybe the projection is a a certain IR frequency, and your classes let you pick up that frequency. That way the person sitting next to you isn't as likely to be nosy.
Personally I think that the ones that display out in the real world are nice, but totally unnecessary. If you have a way to display directly to the eyes (glasses, contacts, implant) then you can see anything you want without it being projected anywhere. And you can connect to other people through a wireless network allowing them to see what you are seeing if they like.
@tcolguin I agree 100%. Popsci showed some goggles that shoot a tiny projector right into your eye so you can see real time gps location and things like speed and altitude. it is only made for snow boarding goggles. but I want to buy some for my motorcycle. its perfect for the road. Why project something in front of you when it can already be projected right into your eyes for a REAL HUD.
