I tend not to like fedora... the whole only "opensource" stuff gets to me. Tried it once, couldn't play mp3's out of the box.
But epel seems to cure these problems now adays.
The problem with fedora in general, IMHO, is that their release dates are to quick. Where Debian(stable) and slackware other distros take some time to get system stable. Sure FC is based on red hat, but RH still hasn't even got support for chrome yet, cause chrome libs are too new.
So for a properly run ( stable ) OS, with support for security and SELinux etc thats up to date, I would prefer say Centos or RHEL .... Using Centos at the moment. Although my home pc is a Debian system and also a freebsd box...
i guess if you want the latest for rhel and cant wait for releases, say the coming rhel6 then FC is what you get. but personally I dont think its good at all
IMHO.
