I see headsets like this as a way to have multiple, large, monitors that go away as soon as you aren't using them. After having a big dual-monitor setup for years, about a year and a half ago I got rid of them and work with just my laptop's display. I do this so that my desk doesn't have to have monitors on it, and is more conducive to artistic work and mechanical tinkering.

I don't miss multiple monitors so much, but I do often wish for a larger screen. Not enough to put one in my space, though. That's where my interest in the Vision Pro lies - simply a way to project large, high-fidelity, 2d screens.
