If you follow the link to the left, you can see Kubuntu, which is just like Ubuntu Linux except it's with KDE instead of GNOME. It has the new KDE 3.4 and I'm typing from it right now on my laptop with the live CD. I downloaded it a little while ago and went for the live CD because I don't have an extra box to install on and I must say I'm quite pleased so far.
