I would much prefer it if manufacturers created a multi-screen setup with screens next to each other. I can imagine some form of folding or attachment mechanism that converts a single screen laptop to dual or triple screen. Since going "laptop only" many years ago the thing I miss the most is the multi-monitor setup that I used to have and would love it if I was eventually able to recreate this with my laptop.
The idea of a second screen above the keyboard does not appeal to me. I have a Macbook Pro with a touch bar and in general I dislike it (even though I have written a custom dock for it, which allows me to reclaim some main screen real estate from the macOS Dock). I understand that this new MSFT screen is bigger and potentially more useful, but the problem of having to look down on the second screen above the keyboard would still be there.
Thank you. This looks exactly like what I had in mind.
EDIT: Another alternative would be to be able to slide the main screen halfway to the side thus allowing a second screen next to it for a dual screen setup.

(I am aware of macOS Sidecar.)
