RofE answer is closest to mine.
The reason I observe that so many people have Windows installed is because they need Windows compatibility. Most people who do this need to satisfy either a customer or an employer. I have found that satisfying an employer is often in irrational process - the very existence of the Windows OS is what satisfies him, not any actual compatibility.
I love my Macs. I tolerate my Windows (aside from Vista which was an unmitigated disaster all around). I’m not a Windows hater. It’s just not as good. I think the main advantage of Windows is to prevent Apple from having a monopoly and getting soft and lazy.
(If sheer numbers were proof of anything, that would mean the climate change crowd is right.)
I’m glad you have an open mind.
“Good” is personal either way. My great grandson is into games. He won’t run anything but Windows. My granddaughter likes Mac’s because she does a lot of graphics work. They’re both happy with what tools they have.
Both are tools for the trade. It’s like arguing over whether Snap-On or Lyle tools are better than the other. Both get the job done. Both have pluses and minuses.
And MacDonalds is a gourmet restaurant.
