I have an x1 6th gen running freebsd. I am a little disappointed with how it's been falling apart. SSD failed early last year. Lost contact with a usb c port a few months after that. LCD has a vertical gray line. Some paint started chipping off around the trackpad.
I will probably replace it with another X1 because I am a masochist. But I do wish it were a bit more sturdy. Other than that, I like the size and hardware support.
All this is very unlikely for a ThinkPad which can be bought with a 5 year warranty and is military-grade tested. Before buying one I have spoken with a licensed service partner in Frankfurt, Germany and he told me, they rarely get any ThinkPads to repair but they constantly get other Lenovo brands to repair. And this is Frankfurt, where you will see only ThinkPads as business laptops in banks...
I googled some of these issues as I faced them and I often found others hitting the same.
It seems like the particular model of SSD I got had a lot of issues for many users. The USB C port coming loose is also something I found other people facing.
Maybe X1 Carbon is more shoddy or fragile than other lines.
The display on my 6th gen has developed flickering issues after only a year and half of light usage. I think the quality on these has gone down a lot recently.
I bought a T25 specifically for the keyboard, the rubberized coating is already wearing off on the palm rest, the screen has this whitish spot that’s brighter than any other part of the screen now, and I found out the stupid thing is held together by clips. I feel like a complete moron.
