To be at all interesting, this would have to have a good keyboard (as in the 2015 MBP), and an optional touchbar.
I used to keep them on my desk partly as screen estate, now keep the lid closed, leave it under the desk and use a bluetooth keyboard in the hope it'll survive.
The whole concept makes no sense. "Don't look at the computer's screen when you work, look down at your keyboard instead!" It is like an anti-touch typing gimmick, the tagline should be "become a worse typelist today!"
My ideal MBP has a touch screen, no touch bar, the old smaller trackpad, and better keyboard, in a form factor something like a Surface Pro.
