KDE 4: Key Improvements, User Tips
"After three weeks of using KDE 4 on my laptop, I continue to find new features and changes. I am aware of the dictionary of special names that make up the back end of the new KDE - Oxygen, Plasma, Phonon, and the rest - but just as often as the major features, it's the little items that I find welcome as much as the large ones. Increasingly, I'm looking at KDE 4 as a statement about what a desktop should be, and contrasting it with my own ideas on the subject."
