.... Some.... crap.... OS...............
You really just said that?
Linux is the most consistently and well-supported OS out there, simply because it is OPEN SOURCE SOFTWARE. ;D OSS is the angel that shall defeat Mac OS and Windows hopefully sooner than later.
Linux is not only free, but being open-source, is constantly updated/improved/fixed by all sorts of people, not one bloody company. And you can use really ay of Linux's many installations/versions. From Fedora to RedHat to others, Linux is widely considered the most versatile OS out there. Only issue is, like Mac OS, not every game is coded to also support Linux, however more and more have been and the support has greatly improved.
