Kubuntu is awesome!
Why do many people use Gnome as their window manager for Linux? It seems Ubuntu.com markets the distribution which contains Gnome pre-installed. For example, the live CD contains Gnome and for this reason many new users seem to think this is their limitation as far desktop interface goes.
However if there are users who are transitioning from Window to Linux for the first time, then KDE is probably a more suitable candidate for it’s familiar style to Windows and ease of moving around.
Gnome feels more of a Unix desktop for average Linux users but with KDE, new users would immediately find themselves very comfortable with it.
Just click on the big “K” icon and you’ll see the familiar look and feel that Windows has. So my advice for what it’s worth is to give KDE a try. Download the Kubuntu distribution instead and give it a shot instead of the default distribution. If you already have Ubuntu installed and want to give KDE a try, simply type:
sudo apt-get install kubuntu-desktop
You can decide to use kdm (KDE) or gdm (Gnome) as your default but you can keep it as gdm for now and if you like KDE more, you can always make it a default later. The login process usually asks if you want to make KDE your default or not.
If you find yourself not liking KDE, then simply remove by typing:
sudo aptitude remove kubuntu-desktop
Enjoy KDE, I am.
