That's funny that is exactly what puts me squarely in the Ubuntu camp. The community is large and full of enthusiastic albeit a little newbish community. They have an audience of new users and almost any issue you can think of will have been encountered and discussed in their forums. Meanwhile I have yet to here anything either in the forums or from Fedora about the issues installing the distro because of a 4 year old promise controller that worked rather well in Fedora 1-4 but now hasn't worked for the last 3 versions.
