Works with Linux out of the box as Dell made all of the driver's work for their developer edition's in Ubuntu. Battery life and and the 3200x1800 screen are phenomenal. Well made and Dell's warranty process is actually fairly good. It's no Apple warranty, but does the job.
I’m, at-best, a mid-level Linux user and I’m coming from MacOS.
I bought a Lenovo Carbon X1 4th gen a few months ago. I was originally going to keep a Windows partition, but wiped Windows 10 Home after about 20 min. The fresh install of Linux Mint was even simpler than expected. I’ve been really enjoying Linux ever since, with the only issue being the HiDPI support mentioned elsewhere ... a 1.5x would be perfect and once that happens, I’d recommend my build even to my parents who are long-time mac/windows users.
FWIW, I run openSuse Tumbleweed on an Asus Zenbook; all in all, it has worked very well. I have the low-end model with a Core m3 CPU, so it's not blazingly fast, but it plays 1080p videos smoothly.
The only problem I had I might blame Linux for was that it randomly dropped the connection to my Bluetooth headset, and it took a reboot to connect the headset again.
I've used Linux on the desktop and laptop since about 2000, always with thinkpads.
Back in the late 90s there were genuine hurdles to do with Linux desktops, my 1999 desktop didn't work in X with redhat 5.2 because of the graphics card.
Today's when most productivity programs are web based, and so much more is cross platform, its far easier to run Linux than windows.
