I agree, but on these discussions, that subset of developers just gets packaged into developers as whole, as if there wasn't anything else.

Personally I know UNIX since Xenix days, do have a vast experience across UNIX variants, use it in some form in many projects, but rather use OS X and Windows environment.

For strange as it may seem, some of us are actually happier with the GUI developer tooling culture of OS X, Windows, Android, iOS.
