More generally: driver support on par with Windows. To be fair, Linux has come a long way and driver support is pretty good most of the time. But if you happen upon a piece of hardware that does have driver issues, you’re still in a world of shit, with no or no easy fix.
Case in point, I have been battling with a weird S3 sleep bug on Lenovo Yoga L13 Gen 2 notebooks recently. I’ve come to the conclusion that it’s not even a kernel error, but something in Lenovo’s mainboard/BIOS firmware. Fix: write Lenovo an email and hope they’ll fix the firmware of a 5-years-old just for desktop Linux use. (And, no, I’m not under the illusion that this is going to happen.)
