100% stable for me at the level of any other linux machine. True the USB-C display doesn't (officially) work yet but I have 0 issues with the HDMI.

I've been daily driving it for months with no blockers. You can tell Linux uses the battery less efficiently than MacOS though so that's good to know.

So, 97% stable then? (Downvote me but it's true.)
