I`m a little disapointed with Ubuntu also. It never worked well with my video (the screen got a bit streched in some modes), QuickTime movies never worked nice and I had some strange problems recognizing my second HD with Windows.
Last week it just stopped working, so I`ve reformated the hard drive, and made one partition with good and old Kurumin and another with AROS.
Kurumin always worked nice on my machine, and AROS in the hard drive is way better than in the live CD
