I am currently running GNOME 3.0.1 with Fedora 15, and that too on fallback mode

. I tried my best to get it to run in the normal mode, but I wasn't able to.
I finally decided to try KDE instead. When I tried
Code:
yum install @kde-desktop
or
Code:
yum groupinstall "KDE-desktop"
(same thing), it shows a 500 MB+ download. I do not want to download a 500 MB version of KDE.
On trying
Code:
yum group install "Critical Path (KDE)"
it shows me a total download size of around 150 MB. But It does not seem to contain any KDE apps. It does not even contain a
network manager!!
I am confused. will I be able to get a full desktop experience with a minimal install of KDE?

What apps and stuff will I get with the critical path install? Will I be able to run GNOME apps on KDE?
Help!!!!!!!!
