Well, you can always project the virtual laptop's screen on a pizza box or a wall or something like that. But I agree in general. I'd prefer a foldable laptop, but I doubt the technology for something like that is anywhere near, while this AR laptop could be made tomorrow. There already are virtual machines made for mobile phones, all that is left is connecting them to AR glasses and voila.
Walls and pizza boxes aren't sufficiently smooth or reflective to use as projection screens for real work. An AR laptop couldn't be made tomorrow because the glasses exist only in limited prototype form with poor display quality.
