Pervasive contempt

I have to say that I'm confused by the GNOME 3 and KDE 4 notion of activities. I also tend to group my activities by workspace - it's arguably the most powerful feature of KDE 3 and earlier that the proprietary environments never supported out of the box - and being able to jump to a workspace using Ctrl-Fn is incredibly convenient and puts that increasingly neglected row of function keys to some use.
