Please, please, check your facts before flaming...
C'mon guys, if you want to argue the point at least do so from a rational and reasonably accurate standpoint...

"Worse for Apple, Pystar only edited their own copyrighted works and not the works of Apple." Doesn't matter, not with DMCA. IANAL but if they have edited 'their own' works (remember they also ripped off a third party's BIOS adapter code) to circumnavigate copyright protection (e.g. to emulate the Trusted Platform Module on every Apple motherboard that prevents OS X running on non-Apple hardware) then they have still committed some kind of civil act in breach of DMCA and the Apple suit stands. Smart move adding this point to the suit by Apple.

When you buy a car you own the car. When you buy software, you don't own it. If you bother to read the licence that comes with it, you are actually buying the right to use it. That is how all software is sold. If you don't like it, don't buy any software sold in this way. That includes Windows, Office, and all your favourite games.
Apple are not telling you what you can and can't do with your Mac. They've merely worded their licence to make it a violation to run your copy of OS X on non-Apple hardware. The thing that everybody forgets is that you've not bought the software. You've bought the packaging, DVD and manuals, and the right to use the software within the terms of the licence agreement. Using the software without agreeing is almost certainly a violation of the agreement because you may only use it by agreeing to do so within the licence terms. Or return the unopened and unused software for a refund.
Software has been sold this way since the year dot - I remember the RML 380Zs we had in secondary schools in the late 70's stated just this point on the floppy disc that came with the purchase of various versions of RML Basic.
Apple can't stop individuals buying an OS X disc and building a Hackintosh and probably don't care anyway. Why should they - they made a sale they probably wouldn't have otherwise, and the end user will either love the experience so much they go out and buy the real thing, or decide they don't like it - in which case Apple has still made money on the deal. Ditto if the disc is then passed on to others. It's a backward compliment to Apple which might explain why they don't jump on the original authors of the bios adapter software.
They do care when a company tries to swing a very large axe at their business model, promoting mass violation of the EULA for profit and, probably, violating the DMCA. No company on earth would stand by while a competitor shafts them in a way that is illegal. Psystar pre-install the operating system so THEY, not the end user, are violating the licence and DMCA.

Apple design everything themselves, using off the shelf chipsets. In that way they are as much a hardware manufacturer as HP or Dell, And like HP and Dell, everything is manufactured in China or other far eastern countries. You cannot buy a 'Mac compatible' motherboard, Apple's motherboards are not staock Intel boards which is why you need a 'fudge' layer of code to adapt a 'standard' BIOS and emulate the Trusted Platform Module which is a piece of hardware that identifies the motherboard as a Mac motherboard. See the osx86project.org FAQ for more information.
Personally, I'd like to see Apple make the OS available to third parties. I don't see them doing it because their business model is all about selling products that give them downstream revenue generation. If you have a Mac that you can use for five years, and it will perform well with new versions of OS X, you're going to buy the newer version. If on the other hand they did a Vista and you needed to buy buckets of extra memory, sales would be lower...
