Hi

"The security features in Fedora make it one of my favorite Linux
distributions. And that is partly why it is in my list of the top 6 KDE
distributions of 2011, even though it takes some tweaking to get it to
the it just works state. I will take the security advantages of an
operating system over any user-friendliness weaknesses, provided those
user-friendliness weaknesses are not show stoppers."
