Edit: maybe it would help you to level out your perspective by thinking about some reasons why almost every business on the planet runs Windows and not Mac.
Every is a bit strong, but...
Well, IBM wanted to use an OS called CP/M and was buying a lot of products from Microsoft. Something stupid happened and then IBM bought their OS from Microsoft. Microsoft was allowed to license it and Compaq figured out a work around for the BIOS issues. Thus DOS became the big thing because of IBM then all the other PC companies. Apple totally flubbed the Apple III, and Commodore didn't retain their leading market share. IBM then completely failed to follow-up with OS/2 (seems working with Microsoft to compete against Microsoft Windows is not a healthy move).
DOS begat Windows which begat Windows NT, and the software was good enough. I can buy a PC from more than one company and they have a lot of non-technical, business support. Microsoft doing a bit of cheating probably helped. It actually helps sell support contracts to have some problematic areas in your software which generates an amazing ecosystem that businesses understand (paying someone to be responsible is understandable).
A lot more people drive Kia than BMW, but I really wouldn't argue Kia is a better built car.
* Multidesktop
* PDF support baked into OS
He's right with these.
I now solely use the touchpad on my MBPr. I cannot see myself ever switching back to a mouse. Having been a mouse user for 16 years!
The ability to do a 3 finger swipe and switch to another virtual desktop in a split second is awesome. Is this possible on Windows? I don't know.
I was working on a Windows 10 machine yesterday and PDFs opened with Edge. Again, I don't know if it's right or not.
Edit: Every business on the planet runs Office, and they used to all run Exchange, Outlook and SharePoint. They got Windows as a side effect.
I agree. :)
Maybe those other shitty operating systems makers should try harder if they want to replace Windows. It won't happen though because none of them care about their business customers as much as Microsoft does.
Here it is again: Everything that person stated was either incorrect or extremely insignificant because obviously none of those reasons have affected Windows very significant market share.
EDIT: What I don't have time for anymore is refuting every person's laundry list of nit-picks.
