I’m quite optimistic about the headset, but I think one widespread misconception about it is that the biggest feature will be using it as a big monitor for your Mac (or to what movies). No one wants to wear a headset just to have a big projected screen, with much lower PPI (even with 4K/eye), small focused area, etc. Movies (and productivity apps) won’t be a projected rectangle on the wall, but immersive, full field-of-view experiences. I’ve head lots of comments about AAA games, but just playing at 100 inches doesn’t make much difference, it’s not a big leap forward. The big opportunity is to create realistic first person experiences — even games with simple mechanics would be amazing.
I’m not ruling out that it might be an option, but not the big thing. It reminds me of the original iPad: people thought it was going to run macOS, have a lot of ports, x86 processor, etc. — it was just meant to be a touch Mac, but it would have failed in that case, because the hardware, use context, interface precision, etc. would make it worse than a Mac. Instead, it found its own way. Same with the headset: I think it would fail as a Mac/iPad/iPhone replacement. Instead, it will be a new device that excels at some activities where the rest of devices can’t.
