Also not exactly something I would rush out to have - but it is ground-breaking. It is your computer writ large. I could see myself enjoying looking at the grand canyon superimposed on my wall. Or typing up a report, cocooned away from distractions (except those in the glasses themselves). Spatial computing - hmm. Finally, Cmd Z with my hand in space might actually undo something. ;^)
I spent 5 minutes in an a game based headset quite a while ago and did not like it at all, the loosing of all sense of the real world made me nauseous. Looking at others flailing around with the googles on is always a laugh. Part of the problem there was that I had to move and interact or the monsters would get me. That experience makes me wary of the whole Oculus/Goggle/Headset idea. The intriguing thing on the Vision Pro is that participation seems less stressful. There may be useful things to do in there.
One of the questions I have is what happens to the "screen" when you bend down to get popcorn or look to the left to see who just came in the door. The video (not really a demo - I think it is all cgi) shows everything staying put. That is some impressive tech!
Apple Silicon has really opened the door.
