Working on that. After making myself use K4 for a week, I'm starting to find my way around it. It is still unfamiliar territory. Kinda peaceful though.. nothing happens quickly. I have time to go start the coffee pot between pushing the power button and the desktop settling down. Things slide, or fade, in and out. Lots of informational bubbles floating around, usually covering what I thought I wanted to see. The hdd light shows continuous background activity, assuring me that I get good use out of the computing power I paid for... nice chill pill.
Next step was to try on a very minimal install, unchecking everything except X11. Even after 545 MB of downloads and 1.7G installed, there are obviously some pieces missing, as I only get a terminal window. Gonna try to come up with a list of what it takes to make a full desktop.
