During the last few days I have read a few interesting article about the upcoming fourth version of KDE.
What I have read there made me really go "Wow!", because it sounds great.

Unfortunately, Ubuntu is becoming more and more of a disappointment lately. First they start shipping non-free software by default, then the edgy upgrade turns into a disaster and now I read about plans for including more non-free software and a 3D desktop by default in feisty (the next Ubuntu after edgy). To be honest, ever since I've seen the Feisty Fawn announcement I've been wondering what does the focus on "multimedia enablement and desktop effects" imply, the basic suspicion being will it include more non-free software by default?
