K Desktop Enviroment 4

KDE4

Recently i got stuck in using free OS . now i prefer Centos to FreeBSD.
Centos is good for it desktop enviroment like GNOME or KDE, while BSD is hard to install KDE or GNOME.
here the KDE4 has released.
it looks familiar to Windos vista interface.
and now Fedora 9 is going to release in 5 days.
with Fedora 9, the desktop enviroment is expected to be better than Centos 5.
but some said that Centos is good for server while Fedora is good for application use.
