Mark Shuttleworth: No, not at all. I need to maintain a fairly even perspective across the project, and we do have a lot of KDE users in the broader project and in the community as a whole. So I tend to run both.
My laptop runs a Gnome-based environment, the traditional Ubuntu environment, and thats my primary computing environment. My desktop, which I use for development when Im at home basically, thats a KDE-based desktop, so I use Kubuntu on that.
And Im also running Xubuntu [ZOO-boon-too], which is an xfce-based environment, but only on a specialist computer where it particularly suits the hardware and the application that I have there.
