It's incredible the sound and fury generated by version numbers. Ubuntu is almost there if they would just drop the rather silly animal names and stick with 10.04, 10.10, 11.4, 11.10 et cetera. Also having such a easy to remember and unique string makes searching for support and technical questions nice.
Ubuntu's animal names make it easier to search for support and technical questions-- "maverick", "natty", and "lucid" are all much more likely to be associated with Ubuntu than numbers like 10.10.
