While not the most popular distro available, Fedora tries to offset itself from others, like Ubuntu, by adhering to "purist" standards. Fedora only includes software released under a free and open source license, which prevents them from including a lot of de-facto features you might find elsewhere.
Proprietary video and audio codecs like mp3 support, Nvidia and AMD drivers, DVD playback, flash and much more do not make a default appearance in Fedora as a result. All of these can be installed, of course, at the user's discretion, but it gives you an idea of just how much software many people take for granted is not supplied truly for "free".
If you are interested in downloading Fedora 12, it is available through their site.
