These have been around for several years. They are cool for airplanes and such but it isn't revolutionary.

I've never actually used a pair (can you describe them as a pair?) but I've known about them for a while. They do seem like a neat idea, but for me personally I'd much rather be able to see the machine in front of me along with the rest of the room- I'm paranoid like that. Has anyone on here actually got any? I'm sure many have used them though. I'd like to, just to see what it's like.
