Well... i just tried the newly made Fedora after not using redhat since when RH8 was released (i used it for a week or two).
First of all ill say the good points ive found with it. The installer is one of the best ive used, although i thought it was missing something until it asked me to create a user at bootup. It detected my hardware flawlessly and setup everything fine except my network card which was easy to fix.
I found that all the graphical utilities for setting up NFS, Samba, servers, etc, etc, were really handy although i merely took a look at them and didnt use them. Setting up X using a gui is rather odd feeling after i've been editing XF86Config by hand since i started using Linux.
THe things i didnt like about it is, I logged in to KDE, logged into Gnome... and i couldnt tell which i was in. They *are* different window managers they should look different. I absolutely hate how all the menu items have names like "Messenger, Browser, etc." So that i can not tell what im actually going to be running when i click it. And switching the gaim icon with the horrid looking smiley icon was really low .
....i still have it on my comp and will use it occasionally, but im still using slackware exclusively
