I haven't followed the TPM issue/nonissue, but I would point out that if it is "against the law to install Mac OS on anything other than an official Apple machine" then it is not an Apple stipulation, but a matter of federal or state law. And I strongly doubt that the US government has made it illegal to install MacOS X on a non-Apple-specific hardware platform. Perhaps you meant that it's a stipulation in the end-user-license-agreement (EULA) for MacOS X?
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
