Step-by-step tutorial with screenshots!KDE 4.1 is finally out today, as you probably already know, and it comes with a lot of innovations for the Linux desktop. KDE 4 is the next generation of the popular K Desktop Environment, which seeks to fulfill the need for a powerful yet easy-to-use desktop, for both personal and enterprise computing. The new version provides increased stability over the first KDE 4 version and more eye candy!
