Maybe that's why I still stick with openSUSE and never got tempted to try something else. When KDE 4 came out, openSUSE just didn't switch. They offered it for those who wanted to try but otherwise stayed with 3.5. Only when KDE 4.3 came out, they switched and it was a good decision. And even afterwards 3.5 was available for users. Same for PulseAudio: they introduced it when it was usable already but still it was (and is AFAIK) completely optional. It's just one command to turn it off or on.
