A major limitation for using VR devices as "virtual monitors" has been the screen resolution. Vision Pro appears to have significantly higher resolution than anything available on the market right now; in your experience, was the resolution high enough for the pixels to disappear and not be a distraction, especially when e.g. reading text? Have you used other VR headsets to compare it to?
I've used other VR headsets and it's significantly better than everything I've tried. You'll be able to put up virtual monitors at the same density as real life and read stuff fine, I couldn't really discern pixels at all. Reading physical monitors through passthrough is a bit harder (I increased text size a few points when I needed to do this) but isn't really something you'd do for actual work.
The idea of looking at real screens in passthrough didn't even occur to me.
