Yeah, that's not great. I guess that's slightly useful, but what I'm looking for is the ability is more like virtual desktops but being able to place each desktop into physical space. Being able to do that with individual windows would be even better, but I'd be fine with the virtual desktops. If Vision Pro can do Airplay, then I don't know why Apple decided not to do an integration with virtual desktops from macOS. Maybe they will, but not having that at day one is puzzling to me. Without that, it seems we've got yet another AR/VR device that is a glorified tech demo. I really hope that it gets better (and less expensive) than what we are currently seeing.
I've been keeping an eye on the Simula One for some time, it does what I think you're looking for[1]. I have to assume outside of the Apple ecosystem this type of this is already possible with existing VR headsets, but the closest I've seen is Virtual Desktop[2].
I guess for the Apple ecosystem we've gotta wait for some software updates to make it more useful. Not that I can justify paying my own money for the Vision Pro or Simula One.
I'm sure this will be possible in future Vision Pro devices, main issue right now is probably performance. Macbook Pros already can only push to 2-3 monitors (albeit at higher resolution) and the Vision Pro is also running its own apps simultaneously alongside the Mac window (curious if it is the Mac or Vision Pro doing compression and other processing work for streaming to the headset). Apple being obsessive about frame rates and performance are likely erring on the side of caution before allowing too much. For example the recent downgrade from 1080p to 720p when it comes to streaming the Vision Pro screen to other devices.
