I've seen Ubuntu at the top of DistroWatch for some time. I've avoided it for the usual reasons: I don't know how to pronounce it, I didn't have a machine conveniently available to test it on, and so on.
Ubuntu is a single CD. Installation was quick and simple. Apparently some folks don't like that the install is text based - sheesh, is it so hard to live without a mouse during the install? To me, it makes perfect sense: there's darn little that requires mousing.
