Honestly though, gamedevs really are among the biggest Windows stalwarts due to SDK's and older 3d software.
Only groups of developers more tied to Windows that I can think of are probably embedded people tied due to weird hardware SDK's and Windows Active Directory dependent enterprise people.
Outside of that almost everyone hip seems to want a Mac.
80% of the desktop market has to have their applications developed by someone, at least until software replicators replace them.
Everyone hip alright, or at least those that would dream to earn a salary big enough to afford Apple taxes.
Remember there are world regions where developers barely make 1 000 euros per month.
