Tux Machines (TM)-specific
A common trend among many of the best developers is to see them posting screenshots running OS X. Many of the best developers, some my personal ‘developer heroes’, have made the switch to OS X.
It’s All About the Mentality
I respect and admire programmers like @migueldeicaza, @mitsuhiko, mandrake, @dhh for all they have accomplished. One thing they all have in common, present day, is running OS X. Mandrake cowrote Enlightenment (which is the original really cool window manager for Linux), Miguel started Gnome, and the majority of code both Mitsuhiko (wrote almost every useful Python library ever) and DHH (Ruby on Rails) write run on Linux backends to say the least.
What are they most known for? Problem solving skills mixed with actually producing / releasing.
