I used Open SuSe for awhile and  i wasn't impressed by AppArmor.  I switched
to fedora largely because i wanted to learn the in's and out's of SELinux. I
expected alot of trouble out of it but haven't had more than a peep or two.
I run it on three machines of my own( Fedora 8) now and i have installed it
for two people who don't care what OS they have and they haven't had any
issues to date with their standard desktop configs. Granted they are not
power users or anything but personally i think its ready for everyone to
have because the odds are they won't notice it . People who use unusual
configurations or are power users may run into an issue but i would expect a
power user  to be able to troubleshoot it without much difficulty. All my
trouble has been caused by my own tinkering with this or that but all of it
has been easily resolved. Perhaps I'm the exception??
