As a ThinkPad user, I disagree. I've been using Linux (Fedora + Arch) on my Z13 Gen 1 for three years now and it's been a first-class experience. Everything worked out-of-the-box, with literally zero issues. I can't think of a single thing that I'd want to improve, from a laptop user's perspective. For me, this is the definitive Linux laptop experience.

I had a similarly good experience with my previous laptop, an HP Elite Dragonfly. Only niggle was that not all bits of firmware was upgradable via fwupd, so I had to ocassionally boot into Windows to do the firmware updates. But other than that, I don't recollect any issues with it either.

And I'm sure the laptop experience is equally good on "native" Linux laptops, such as the ones from System76, Slimbook, Tuxedo etc.

So to make a blanket statement like "'the modern experience' is dogshit sliding down a wet stick for laptops", is pretty disingenuous and very disrespectful towards all the developers who've worked so hard on making Linux viable.
