Yes, XFCE was introduced with FC3, you will have the option to install
it in
Anaconda when you upgrade to FC3. Then, when you logon you can select XFCE as
the session.
XFCE is a light, fast, graphical desktop. It's actually rather nice, see
http://www.xfce.org/
One correction it was available in CD 4 of FC2 too, but there was no
option to install it with Anaconda ;)
