The desktop on a Mac gives you a home, more than the home space on iOS or iPad. Vision gives you the most homey, spacious home yet: your actual home, your actual space (plus virtual environments as well)
From trying it now, one downside is that the virtual environments don’t necessarily feel stable, we can activate them however we like. To have comfort and stabilty, a visionOS user needs to take some time to think about how to set up their space, and where and when to use virtual environments. Without that care, things can feel a bit hectic and random (constantly moving windows around).
