KDE 3.1 RC2 is downloadable in source code form only (only Mandrake released binaries so far, I think). Thus, compiling a large package like KDE is never error free (at least while I'm at the keyboard, it isn't). My current distro favorite of the month is the recent Red Hat 8.0, which sports a spiffy, heavily modified GNOME 2 interface. I have to say, Red Hat 8.0 has become my favorite desktop distro, with Slackware 8.1 being my second favorite desktop distro, and favorite server distro.
