Yeah I agree - an immersive "sleep mask" where someone can lay back and enjoy some private experience while killing time is the use case neither Apple nor Meta seem to be fully embracing yet. Make it lighter, more discrete, easy to slip on and off- and people probably wouldn't be too embarrassed to jump in.
I'm reminded a bit of the Sony HMZ-T1 and Glasstron. I think the trouble is Meta is interested in use cases that drive data generation and "social" experiences, and apple is looking for the next iPhone/app store versus what the tech is best suited to.
