Recently Asus dropped new ROG tablet which looks powerful enough, but I don’t know if linux would work on it.
Edit: it’s ROG Flow Z13
They have a mini PC "Star Labs Byte".
Basically a laptop sans keyboard, display, and internal battery.
Is there a Linux tablet that can both act like a tablet and also be the screen (and heart) of a developers "laptop" if paired with a external keyboard?
Some kind of detachable "hub" that gives more IO options is optional.
