Part of the problem is the naming scheme. We have OS X 10.0, 10.1, 10.2, 10.3. Jaguar being OS X 10.2.x. Well, really the X and the 10 are the same. Panther is REALLY OS X.3.0. I would equate the term "OS X" to the old term "Mac OS". You had Mac OS 7, Mac OS 8, etc. Now you have OS X 2.0, OS X 3.0, etc.
In my mind, if we were following the old numbering scheme, Panther would be Mac OS 13.
Apple's new number scheme is a bit confusing, by their reconing, if said aloud, Panther is "Mac oh-ess ten ten-point-three." See the silliness? But in fact OS X is not the tenth version of the Mac OS but a totally new OS that deserved to start at 1.0 (especially since 10.0 seems to have sucked hard). Maybe it's just me.
