If Psystar Wins, the Homebrew Cloners Lose
If people think a Psystar win will force Apple to license MacOS X for beige boxes, think again.
Apple will simply stop selling MacOS X starting with Snow Leopard. You get a box, the OS will be preloaded. System updates will work as usual. Want a new release? Take your machine into an Apple Store (or via mail) and for a nominal service charge (around $130, natch) they'll upgrade your machine. They'll probably make you sign a contract, too; no EULA problems there since you actively agreed. Obviously, they have the right to refuse to service a competitor's machine.
That won't stop people from making and distributing images of a clean MacOS X drive, but since those will be patently illegal copies Apple won't care; they'll just sic the BSA on the distributors. Psystar will have no options open: Leopard will no longer be available via retail, and Snow Leopard won't be available period.
Expect new machines to come with the TPM fully activated to limit the cloning. Also expect the MacMacs to vigorously defend the practice even though it sucks for everyone else, and the Freetards to claim "Well, now I'm switching to Linux!" even though Apple couldn't care less about them (which causes them to hate Apple more). Finally, with the death of the EULA, expect to be forced to sign a contract for ANY software since companies won't be able to enforce their terms any other way.
Apple isn't going to slit their own throat to make the customer's life easier; nor should they. Most of their customers wouldn't upgrade anyway: the average consumer is content with the OS that comes with the machine.
