I have been using Xubuntu on my Mini 9 for a couple of days now and I am not sure I can recommend it over standard Ubuntu. Gnome is pretty good with sizing dialog boxes to fit the 1024x600 screen, Xfce not so much. The first thing you will want to do even before fixing the audio is reduce the system font to 7, it does not totally fix the problem, but it makes things usable. Xubuntu initial foot print is close to 1.5 GB, which is great, unfortunately, once you update the system, install w32codecs, flash, java, msttfonts and practically anything else, you up to 2+ GB, which is not much of an improvement over Ubuntu. Setting up a dual monitor on Ubuntu is nearly trivial, under Xubuntu, it is a serious pain. The only real advantage I found was I didn't have to remove OpenOffice and install abiword/gnumeric.
