The oddball names aid greatly as search markers. 10.10 is not a great differentiating search term in computing whilst "maverick" (or indeed "meerkat") doesn't often appear alongside "wifi setup" (or whatever) except in pages referring to ?Ubuntu.
"Oneiric ocelot" seems to be going too far in searching out little used vocab though - who knows how to pronounce or spell oneiric?
>[Mark:] "The pronunciation is like “an-EAR-rick”."
But dictionary.com tells me it should be "oh-nay-rick" and their sound bite is "oh-nai-rik" (in my pronounciation). Given the Greek origins (http://en.wikipedia.org/wiki/Oneiros) I'd go with on-eye-ross and hence on-eye-rick.
Ocelot: The ocelot ranges from 68 to 100 centimetres (27 to 39 in) in length, plus 26 to 45 centimetres (10 to 18 in) tail length, and typically weighs 8 to 18 kilograms (18 to 40 lb)
Leopard: Head and body length is between 125 and 165 cm (49 and 65 in), and the tail reaches 60 to 110 cm (24 to 43 in). Shoulder height is 45 to 80 cm (18 to 31 in). Males are about 30% larger than females, weighing 30 to 91 kg (66 to 200 lb) compared to 23 to 60 kg (51 to 130 lb) for females.
It's much easier to remember 10.10 (released 2010 October) than whatever year Monkey, Bat, Cow or Hedgehog came out.
