"Unlike Gnome's ease of use, KDE offers many more configurations options
which makes it complicated to be used by an average user. So, the lethal
combination of Fedora and KDE can be 'dream PC' for and advanced user
but at the same time the same combination is a recopy for disappointment
for an average user."
