Anyone played with this? I'm a GNOME person, but this is interesting.
Me too. I always found KDE a little to "flashy" and more resource intensive. It works better for Windows users though, it's a little more familiar to them than gnome.
There is also a KDE project for OS X which I would imagine was a little easier to port based on OS X's unix base (POSIX compliant Open Brand UNIX 03 registered) and X11 available on the disc.
