I've installed and have been trying to use F9 on one of my machines for a while now, and if you are thinking of trying it I would suggest that you do not.   It is the worst release in a very long time, maybe of all time for Fedora.  I have used Fedora since it started, and there is something fundamentally worse about this release than all the others. 

Just some of the issues: removal of some important configuration options during install, quite unstable wi-fi drivers, terrible GDM, and the removal of KDE 3 for what can only be described as the currently dreadful KDE 4 implementation.  Stick to F8 until some of the really significant fixes have been implemented, or maybe skip F9 altogether and wait for F10.  F8 was quite a good release.

KDE4 in particular is disappointing. KDE used to be (pre 4) quite a fast and pragmatic desktop that conformed well to the way one worked.  Very configurable and stable and one could configure it just right so one was free to 'just get the job done'. 

KDE4 is not ready for prime time, it is an alpha release at best in F9.  A giant step back in terms of functionality (a lot of 3.x functionality is missing), stability (crashes frequently), and configurability (many things are simply not configurable).  Reading through the discussions and forums it is clear that the mismanagement of KDE should form a classic example of how to botch a major release.
