Can't wait to read/see reviews of this device. Their presentation looks great, but it is just a mockup/simulation of what it looks like.
Not sure if people realize this, but you don't actually see through the screen, like how Microsoft's HoloLens is. You're just seeing what the cameras see in front of you. How well does it work in a dim room? Are the colors accurate? Do bright lights wash things out?
Showing your face/eyes on the front is cool too, but again, it's just another screen and not your actual face.
