This works on so many levels... just knock off the "10." from any OS X version number, and you have the real version. Rhapsody: Pre-alpha development release. Mac OS X Public Beta: An alpha with the wrong name. Mac OS X 10.0 -> Mac OS X 0: Version zero; the real public beta. Mac OS X 10.1 -> Mac OS X 1: The first genuinely working version, version 1. Mac OS X 10.2 -> Mac OS X 2: Version two; the first good one. Mac OS X 10.3 -> Mac OS X 3: Version three; getting mature now. Makes so much sense, doesn't it? It also explains why they charge a full $129 for a .1 increase in the version number... because it is really a full integer increase (which is obvious, given the hundreds of new features in each .1 increase). if they ever come up with Mac OS Eleven, it'll have to be a radical shift, like with a 3D-holo-interface, or where the whole User folder is stored on the net, or a fully tablet-based-OS, or perhaps direct brainwave input. Ya know... something new.
