I’ve found mine to be really good. They seem to have fixed issues with the trackpad that bothered me.
Only things I’m not keen on are the PgUp, PgDn key positions above the cursor keys and mixing the 4k screen with a 1440 external screen.
I opted to buy it over a Thinkpad because it comes with linux preinstalled and at the time the current X1C had some issues, as I recall. I think whatever it was has now been fixed but it’s still officially unsupported hardware in that you’re not paying Lenovo to support it.
