Hi Angie,
I'm glad that you finally found a solution (a workaround?) for your problem. As
you may know, Linux in general is all the same. I feel that I'm about to preach
to the choir here, but w/e.
Really, all that can possibly differ from one distro to the other is ...
1) Package system. (yes, no, type?)
2) Filesystem structure.
All I'm trying to say is, what really differs from a distro to another is you
getting used to different types of applications that practically achieves the
same thing.
Now I'll advise against anything REDHAT for the ideology of REDHAT but
necessarily for the quality (though, APT > YUM any day!), frankly a large
portion of kernel enhancements and security patches comes from REDHAT, but
that's aside from the point.
I'm what you would call a low level nut, I have an intimate crush on Slackware
and the like, however, I just can't use something like that on daily basis, its
counter productive at best. Also I can't stand any desktop environment that has
leaks or too many flashy mumbo-jumbo, so I reseted for XFCE on Ubuntu.
The point is, use/learn something that makes your day lot less harder on you,
CentOS is never meant to be a desktop distro, same goes for Debian (I was a
Debian fanatic back in the day). That reflects greatly on the kind of software
versions you will find in the distro's repo. So far Ubuntu is doing a great job
keeping up with the speed of things, I'm not sure about Fedora, but used it on a
couple of jobs before and it never got in my way too.
All in all, good luck, and I hope you have a better experience with Fedora. :-)
