The KDE folks recently released KDE Software Compilation 4.4 to the public and it totally rocks. I have been using it for the past week and it is the best KDE release so far. The Plasma Desktop Workspace has finally reached a level of maturity and stability that makes it a real pleasure to use; not to mention that you feel a lot more efficient and productive while using the powerful features provided by this environment. The core applications have also been integrated into the Plasma workspace and work well together. The KDE developers are doing a great job improving KDE4 in every release. There are still several places where KDE4 needs improvement but it will surely happen over time. Meanwhile, I will continue using KDE as my primary desktop environment.
