For you odd folks who like that KDE thing, you'll be happy to know that KDE 4.0-alpha1 Released: "Knut" has been released. Highlights are a new visual look, all sorts of cool stuff in the background, new default apps (dolphin for a file manager for example), composite enabled for eyecandy goodness, and much more. Probably still horribly unstable, and it sounds like it's still far from finished, however, I'm happy to see it being released and plan to check this out ASAP! :)
For those of you running Kubuntu, here are the upgrade instructions.
