The problem with a lot of these is they don't run MacOS natively. Maybe it's great hardware (as is a $2200 thinkpad if you buy one now), but I'm not going to use Windows 10 for my mobile workstation.
That's fine and all but the touchpad support on Linux is greatly lacking, though I know there's a project in the works to improve that. I can just as easily run a full screen Debian workstation inside virtualbox on macos with very little performance impact.
And I'm absolutely not going back to a 16:9 aspect ratio 1080p screen, ever.
