Possibly, it does seem that way for web dev at least. There's plenty of programmers out there (the majority?) not doing web dev and never touching Macs however.

Possibly, it does seem that way for web dev at least. There's plenty of programmers out there (the majority?) not doing web dev and never touching Macs however. In a 20 year game development career I've never had cause to use a Mac for work purposes. Perhaps the share of developers using Macs as their primary development machines exceeds their 10% market share of laptops but I doubt it's a majority.
