Hear me out: MS Excel. The one true powerful version only exists on Windows. Another anchor: ODBC drivers. Some good SQL Server connectivity options are only available on Windows.
When your captive audience is accountants, traders, and CFOs, it's quite a moat.
And then, somehow, the desktop Outlook is better on mac than on Windows.
On Windows I can't even easily copy/paste from one email to another. It strips out half the formatting and any colors that were there. Nor can I copy email recipients from an email into a new one.
I tried switching to Windows last year and I just couldn't do it. So now my expensive and fancy powerful laptop collects dust and I'm back to my 5 year old m1 (which is somehow faster, usually).
