Having all the guts stuffed into the display, and if they don’t make it too heavy and the sensors are exact enough, and the adjustment knobs and straps are intuitive enough: sharing the headset around could be more of a thing with this than with competitors. I would feel more comfortable doing that depending on how close I was with the person previously sweating and breathing and blinking all over it, but in an intimate family situation that could be something some people get ok doing (beats shelling out 7k for a pair).
Travelling is an interesting use case becuase the shape of a VR/AR (which I guess together equals MR) headset is so weird. It’s the most un-Apple form factor, and at least for now un-Appleable, by which I mean it will never fit in a manila envelope. Not a problem if you have tons of khakis to pack around a lopsided cylinder and a bellhop carrying the trunk around for you.
Throwing up a stream of your eyes feels like a placeholder that we’re going to be living with for the decades it will take to reduce AR goggles down to the size of actual glasses. We can pretend the thing is see-through for now, and once we’re used to that it just won’t go away, and the tech will be refined to something passive. Maybe!
