And what about the broken glass?

Makes sense to me. Sounds weird but some people don't have the ability to think in 3D. My wife is one such person. For example she can't combine in her head her actual spatial position and surroundings with Google Maps, so she can't use it. Same with those 3D rotation IQ test types of puzzles. I'm sure she wouldn't be able to use spatial computing.

I mean this is just like with all VR headsets. Most people simply dont need to have a screen strapped to their face, let alone at the cost of 3,000 buckaroos

If the user can't figure it out you built it wrong

I see iPhones as hand holders so makes sense older parents bought them and introduced their kids to them. Which again, are being held by the hand on what they can use and not use.

They can't figure out new technology. I'm able to use an iPhone even though I've never had one but opposite can't be said about people using my android. It's weird.
