“I want to make one thing crystal clear - Windows, in some regards, is even worse than Linux and it has its own share of critical problems.”
The list runs long because the problems are real: drivers, regressions, fragmentation and hardware vendors who won’t release data sheets. The author also calls Windows worse in places, which is fair. Android is the usual counterargument, and it only uses the kernel. The year of the Linux desktop keeps getting pushed to next year.
