Windows works for everyone. It’s fine. The question here is how well does it work for some people. A lot of people find macOS better. I haven’t heard a lot of people who specifically prefers Windows to macOS. However, getting a fully functional, often very powerful computer for way less money, getting a specific hardware option not availalable in Apple world or being a PC gamer - are some of several very good reasons to get a PC. But for a lot of people, macOS, macOS apps and the Apple ecosystem is the reason they go to the Mac. Trying to convince these people that somehow Windows is just as good is just like trying to convince people who need, say, high end GPUs that Macs are cool too.
So, it’s not exactly anecdotal, it’s millions of people that don’t want to use Windows. Just like even more people want to use PC hardware and don’t want to use Macs. But if
@Shanghaichica says Windows doesn’t work for them, I believe it.
