The X220 was an amazing machine. I've had a couple of Thinkpad T series over the years and they were my favorite laptops. The keyboards were great.
I'm hoping the trend of more vendors selling Linux laptops will continue. I think there's a good chance that large companies supporting the OS will lead to a more maintenance free / a more stable experience for a wider range of use cases.
I don't dislike Linux. I simply wish it worked better for my purposes. IMO the best OS would have Windows' Mouse drivers and gaming support, MacOS early-mid 2010's Workflow/UI and touchpad drivers, and Linux's everything else. I work with all 3 major OSs on a daily basis and there are things that each of them does better than the others. Interestingly, the thing I find to be poorly implemented on all 3 is Multi-Monitor support.
I mean, I've run into all kinds of issues trying to install Windows as well, including digging through random vendors' websites looking for drivers. But most people's experience is fine, because the laptop vendor provided all of that out-of-the-box.
Well, I have used Linux as a desktop OS consistently since 22 years now. I started with Thinkpads and they did work well for me, and that's what defines my expectations today - that a laptop works without glitch. And the last two laptops I god were supplied by the respective organizations IT department, so they took care that it works.
On the other hand, I am kinda stuck with an Thinkpad X220 because I like the size, the matte display, the great keyboard, and to read my email or work on something in the train, I absolutely do not need more power than it has.
The key for all that is to buy compatible hardware, and research it before spending the money, not after.
