I have X1 Carbon Gen 6 and I love the laptop overall, I’ve been using it for 4 years so far. I don’t mind having fn and ctrl swapped, but my keyboard has also a stupid placement of PrntScr. It’s on the bottom row, right to the space bar. I can’t count times when I accidentally opened spectacle 50 times, because I hold the wrong key.
I have also happened to have a try with some newer thinkpads and they felt like the company made them worse on purpose. The material felt cheap, keyboard choppy and the trackpad absolutely abysmal with its lack of precision.
With the hardware support under Linux… yeah, they do work, but when you pick a new model, expect some missing features, worse power management, quicker thermal throttling etc. For me it significantly improved over time. With 10yo refurbished thinkpads Linux is great though, they say
