It's nearly a year since KDE released the KDE4 desktop. The initial roll-out was rocky for KDE, and while subsequent releases have brought ever increasing stability and enhancements, some KDE users feel it's not quite ready for daily use.
In the beginning the solution -- for the KDE project, and for distributions that ship with KDE, such as Kubuntu -- was fairly simple. Offer both the 3.5.x and 4.x versions, either as a installation option, or through repositories.
At some point, however, a disconnect has to come. Celeste Lyn Paul, a member of the KDE Human-Computer Interaction group, talks a bit about the decisions Kubuntu had to face as Hardy (and its 3.5 desktop option) gave way to Intrepid's 4.1.x only environment.
