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?
My work has been providing an Ubuntu based Linux ThinkPad X1 for over a year and it’s been great not having to deal with MS nonsense. There are some growing pains, but it’s well worth it!
My previous laptop was a $300 Chromebook. It was nice enough, but it was s hassle to have to flash legacy coreboot onto it to run native Linux.
On a ThinkPad you just add your install media and boot that shit up.
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.
