Personally I'd make the monitors the same size as real monitors. So... yeah maybe they'd be HD if they took up 2/3rds of peripheral vision, which would match my current monitors. But you could also have more of them, and handwave them away when you want the table back
And when on the move would be better than... nothing, which is what it's competing against. Look at phones, they're absolutely abysmal for both input and output. But they're mobile. Laptops? They're not as good as desktops.... but they're mobile. Virtual displays? They're mobile, allowing more bandwidth in, it's going to be good
To be clear, it'd be below 720p if you're making them at the same size as an 27" display at the regular distance.
I do completely agree that the promise is there, I've been saying for years that VR/AR is completely pointless as a gaming medium and it's only future is in exactly what Apple is aiming for, here. 4k per eye is just not going to be enough realistically
