Lenovo X1 Carbon. I've been using Linux on it for over 4 years now, with zero complaints. When doing consulting engagements, I also ask my clients to issue a Carbon to me, and without fail they do. Usable keyboard, the "nub", high density screen, long battery life, small size, and light weight. I struggle to see what could be improved about it. When the one I'm typing this on (my personal workhorse) kicks the bucket, it will be replaced by another X1 Carbon. The only caveat is, the 15" "Extreme" model has an NVIDIA GPU, and that's a PITA in Linux, since GPU switching is still an esoteric feature, so your options are either to not use the discrete GPU, or to spend hours following obscure readmes to set it up. And in the latter case it still won't be anywhere near as good as Windows GPU switching, let alone macOS, and will likely break after a software update a few months down the road. But that's easy to avoid: just don't buy the 15" model.
