The thing I ask you to consider is a valid use case may exist for others outside how you use tech.
There's likely little question the vast majority of laptop users use a mouse or trackpad for their day to day.
From a power user perspective:
I'm not aware I can use those keybindings to select text in any iOS app and not just in a shell app?
I'm very well versed with keyboard shortcuts, type 100 wpm, and use vim regularly.
A mouse will always be faster for through administering GUI apps where there are settings screen with many dropdowns and checkboxes on every screen.
I log in to as many remote desktops and vms with a GUI as command line. I interchangeably work between Linux, Mac and Windows in a day.
Selexting text in any iOS app also can't be done by keyboard shortcut as far as I know. The mouse again provides the most precision, and I'm not a huge fan of it. The apple pen might be an admission of the need for precision on iPad for more use cases.
It wouldn't kill Apple to expose the mouse capability so I wouldn't have to consider a surface pro.
The iPad with a mouse would be amazing laptop for most.
