How much will you be able to control your Mac using your eyes and with tapping your fingers together?
Will it be a case of needing to stay with the Mac so you can use its keyboard and trackpad to work with what's on the screen? Will you be able to drag and drop things from Vision OS apps to the Mac screen? I think it's likely you can copy from a Vision OS app and paste in a Mac app, because you can do that from an iPhone.
