Earlier quoted context omitted.
My last 2 company laptop were a Lenovo X1 Carbon G8 and a Lenovo X1 Carbon G9. These machines are so reliable and resilient, no matter how much you travel, they are indestructible. I definitely recommend them.
I would not. I've had an X1C7 for three years now. Numerous Linux driver issues (especially audio), issues restoring from sleep, had the screen replaced twice and the trackpad replaced once. To be fair if you get the on-site repair warranty, that is pretty great.
I am currently still using my old X1C2 from 2014. That's quite reliable by my standards. I would prefer to continue with Lenovo due to reliability and good Linux support (there is a dedicated engineer for that matter who is available on their forums and who help various distributions including Debian and Fedora to make things work). I was waiting for the Gen 10 but battery life seems disappointing on Windows, so I am waiting for people to test on Linux. Gen9 only has FHD+ or 4K+ (too low and too high).
