I'm a distro jockey, and have for the last three years TRIED to install, and use as my main OS, almost every popular linux distrubition. Mint-4.0-KDE, Ubuntu 8.04 & PClinuxOS (in that order) have been the best, by far. "Kubuntu" is a joke, in my opinion, and has been since it's beginning, with install problems, their fear of including "codecs" , etc.etc. "Mint" on the other hand, has always been the install that works out of the box. Period!
Thank You Mint team for a wonderful OS.
