Nah, In my little world, almost everyone I know is using Macs.
I've been working with macs since 1987, and it's kinda like a Canon / Nikon thing for cameras.
Once you get hooked on either, it will be difficult to try to understand the other side.
I've been a Mac user for so long, PCs feel like alien software to me. I've been a Canon guy for so long, I don't understand Nikon's approach to setting up a camera.
It's not impossible to switch, it's just hard. Especially when both get the job done.
For many of the "switches" I saw, I guess it's mostly that a lot of us have been "forced" (job requirements, peer pressure, ...) to use one system, when the other system appealed more to our way of thinking. When that pressure is released, we usually go for what feels comfortable, whether it's PC or Mac.
