Is there a reason they're going to drop KDE? Is that the preference of other admin's or something? Just curious.
That's not to say you can't run other desktops. It's just that RH will no longer support KDE.
Since RH won't support KDE IT depts will not either, because they cannot guarantee that they could solve *every* issue that crops up. If a KDE issue occurs, then the IT depts are on their own.
Most corporations don't like that idea. :)
