I'm using the Thinkpad X1 Carbon 7th generation and I feel like with the latest Ubuntu 20.04 LTS it's finally at the level of usability I want in a Linux laptop. Everything works out of the box, including the speakers, camera, microphone, wifi & bluetooth, and fingerprint reader. I can even use my fingerprint for sudo! (I did have to run one or two commands to get that working though). The trackpad is also great, if a little small. Probably comparable to the Dell's. Also haven't got a chance to test real-world power consumption because I'm stuck at home lately (thank COVID for that) but it seems to be okay.
That's awesome! I just bought the new XPS 13 (9300) with 32gb of ram. Unboxing it today, I've heard it works flawlessly with Ubuntu 20.04 except the fingerprint reader, and Dell says that will be possible later this year.
