Except, AFAIK, pystar machines dont come with "real" OS X. They require either A. OS X to be hacked to run on the machines (aka: your pirated copy) or B. Nonstandard hardware specifically designed to emulate things that PC's cant run.

The latter is much much more of a grey area then the former. However, I think pystar does the former. I remember reading awhile ago that pystar shipped with a legit copy of OS X but a hacked copy installed, so if anyone wanted to reinstall, they would have to send it back and pay $50.
