My own experience has been wonderful. I’ve used ThinkPads with Linux for the past 15 years. Everything that I try works out of the box by default.
It is just wonderful experience. I have honestly nothing bad to say!
Does this sound like an advertisement?
Everything on my Thinkpad T440p works as well as I can reasonably expect it to. Everything from web browsing to light gaming even with my relatively resource heavy Hyprland setup.
