Or, more personal, on this laptop I get shorter battery life (I have it plugged in most of the time so it's tolerable), sometimes it doesn't wake up so I have to always shut it down (tolerable) and bluetooth headset doesn't work (I use wired ones, so tolerable again).
Oh yes, the classic usability problem for the Average User, how could I forget /s

Better points. I also have had issues with bluetooth audio on Linux. Battery life less so.
It becomes usability problem for your users when it becomes too burdensome for ISVs to port their software on your fractured platform. It the whole raison d'etre of technologies like snappy, flatpak or docker that now try to patch this problem.
I hear the same problems about MacOS on brand new Macbooks.
People love it when things just work and for many of them Apple and Windows do just that.
That coquetry of ignorance wasn't cool on Slashdot twenty years ago, what makes you think it's acceptable here?
Microsoft's actions, for which they have been convicted in courts of law all over the world, have set back desktop computing by two decades. A PC clone with e.g. BeOS on it could not be had for money or good words, and the reason was precisely because they killed off competitors with their anti-capitalist, anti-consumer stranglehold on the vendors and markets before the competitors even had a chance to show their quality or lack thereof.
Linux' boon was that it by-passed that system, thriving from the figurative grass roots. It makes little sense – merely in order to take it seriously – to demand to be able to buy a pre-installed Linux.
Edit: Sorry, misread the author. Thought you were the same as I asked the original question. Nevermind that.
