Yeah, no. Maybe with old laptops, but newer laptops still have their fair share of issues. When I bought my thinkpad A485 kernels wouldn't boot without additional parameters, the graphics would freeze at times and cause a hardlock, sleep and hibernation have been fixed and broken again intermittently over several kernel versions, the wifi card's AP mode started causing segfaults in kernel 5.2 due to the driver's rewrite but has since been fixed, the fnlock key LED didn't update properly, which I spent a while debugging and submitted a kernel patch for, and while over the years the fingerprint scanner has been implemented, it's a pain to install and support for fingerprint scanning in linux is still in a very sorry state. Oh and bluetooth still can't connect more than one device at a time, so I had to buy a dongle to connect two joycon controllers.

Granted, I've always had these kinds of issues with new laptops, especially when it came to proprietary nvidia or AMD graphics (before AMDGPU) and I agree it's improved a lot, but I still need to tell people that there's caveats with some (especially newer) laptops.

This seems to me as a more generic problem with newer hardware, not specific to Linux. Likely devices rushed out the door to meet some idiotic deadline, badly specced and with incompletely implemented drivers.

At the end of 2021 I got an EliteBook 845 g8 (Zen 3) that worked completely fine out of the box on Linux (Arch with up-to-date kernel). Every last bit of kit worked perfectly. Bluetooth, IR webcam, fingerprint sensor, light sensor, mute LEDs, etc. On Windows, to this day, the webcam isn't recognized because of some USB chip along the line. There's also a lot of lag when adjusting the display backlight, for some reason.

I also have its cousin, an EB 840 g8 (intel 11th gen). A few days ago I installed Win11 22h2 on it. I was lucky to have had an external mouse, since neither the touchpad nor the track point could be used for setup. And it absolutely needs the latest Intel GPU drivers to correctly output 4k@60 through its HP dock (DP pass-thtough, not DisplayLink). On Linux, the same display setup has worked well since day one. But the mute LEDs are still broken.

Both laptops don't come with integrated wired network, so I have an HP USB dongle (Realtek chip). This works quite well on Linux. On Windows, it initially works well, but then, for some reason, Windows figures it needs to update the driver. Then it gains some interesting failure modes, where from the terminal I can do whatever I want, but Edge keeps thinking the connection is lost.

Had an experience like this several years ago, but with hackintoshing.

On a Dell workstation laptop with a Quadro FX770M GPU (basically a relabeled Geforce 8800M GT), the Nvidia drivers had an issue under XP, Vista, and 7 where if the card downclocked when idle it'd cause Windows to bluescreen. The only fix for this for many years was to disable power saving features on the card, turning the laptop into a furnace even when it was doing nothing.

The proprietary Linux drivers for the card worked better (at least it could idle properly) but occasionally they'd cause your WM to lock up for no apparent reason.

The only thing that ran the card for extended periods without issues, of all things, was hackintoshed OS X. The built-in Nvidia drivers recognized it as an 8800M GT (which had been used in real Macs at some point) and it ran beautifully with power saving and everything. I even used that setup to play WoW on for several years.

The bug in the Windows driver was finally fixed at some point during the Windows 8/10 era, and so now I can run Windows on that laptop without problems, but holy cow it shouldn't have taken a decade (it was manufactured in 2008) for that to happen.
