The out of the box ssh experience on Linux is far superior to windows, ssh mounting of disks, easy scp and rsync access without jumping through hoops. To me, thinking of doing my job from a windows box sounds painful.
I'd imagine these necessary tools for Linux server dev/admin are also readily available on Mac, if not installed already. Now, is that worth the price delta? Probably not, but given the sparsity of pre installed, supported Linux hardware I can potentially see the appeal.
This is why in hindsight it was a bad idea for Microsoft to never been serious about POSIX subsystem on the Windows NT linage.
That is why I even bothered with GNU/Linux to start with.
OS X adoption by UNIX crowd proved the point that for a large majority of development community, GNU/Linux itself is irrelevant, what they care about is a POSIX like experience.
Hence Microsoft learning by their Windows NT/POSIX management mistakes, and creating WSL to fill that gap.
For those of us running Virtual Box and VMWare for years, it only brings the convinience of one product less to care about.
