KDE is going through one of the most radical design, performance and feature shakeup in the history of it’s development. All in the name of a new interface called plasma. I have never been much of a KDE user, ocassianally that I have used this interface was only because I was forced to and nothing else was available in the system or the distro. But now the new look and feel of KDE has made it almost impossible for me to not take a stab at migrating to KDE.
