At one of my jobs, I had a Mac, Windows desktop, and UNIX (Solaris) workstation on my desk.
When I moved overseas, Macs were still 2x to 3x the price they were in the US and support was VERY spotty in Eastern Europe, so I switched to Windows for most the time I lived there (7+ years).
Some OSes are good at specific things. Some are bad at everything. Windows is the latter.
