What is the value of "win" in the above sentence? Because for me it's much more useful than either Windows or OSX for development. It won me for package management and for being very similar to the actual deployment environment. Even changing the desktop environment is easy - an "apt-get install" does the trick.

I don't care about achieving desktop dominance - the desktop is going the way of the dodo for most people and for everything that's doesn't sit on a desk or has an Apple logo, Linux is the dominant OS. I'm at home now and there are 9 machines running Linux (phones, e-readers, tablet, router, modem, notebooks) and 5 that don't (Macs, iPod and iPhone).
