Books about Ocelots

OS X began the use of using it’s development code names as marketing tools with verion 10.2 (Jaguar), prior editions were marketed as Version 10 and Version 10.1 while engineers and developers referred to these versions by their project or code names, Version 10 was code named internally as Cheetah and Version 10.1 was known internally as Puma.
We know from Wikipedia entries that Apple’s marketing team decided to use the code name Jaguar after huge buzzprior to the release of 10.2. 10.3 was then marketed as Panther and 10.4 as Tiger. By now, people have heard that the impending version of 10.5 is known as Leopard, in fact, Leopard is a much more familiar name for the upcoming release.
A client today suggested we may see Ocelot as the name for the Leopard’s successor, an eduacated guess and a most interesing name for the next iteration of OS X, the truth however, may be more mundane, Trademark filings show Apple has trademarks already on two neat names, Lynx and Cougar.

With all of that cleared up, we can speculate that Apple wouldn’t use sequential code names beginning with the same letter, namely L, thereby giving us the probable code name (and marketing name) of 10.6, Cougar.

The future of OS X is wide open though, viewers of the wonderful high definition nature series will have gained glimpses of some of the most impressive and elusive big cats roaming this planet, can anyone comment here on what names they expect or think we might see?
