Having a good time with #FreeBSD and #sway (wayland tiling compositor) on my thinkpad X260.
As long as you read the pertinent sections of the docs, it's quite easy to get going on a Thinkpad. Some things I haven't figured out yet, like routing audio through the headphone jack on this hardware, or bluetooth anything.
If you set your expectations to roughly 1999-era Linux, it's an absolute blast, and daily-driveable (again depending on your expectations).
I'd never try running Steam, though. That's masochistic. XD
And I do tend to look for ways to advance my computer masochism.
