Yes jquintan, go to the Apple store, pick up a copy of Mac OS X and attempt to run it on off the shelf hardware. Let me know when you succeed using the out of the box disk.
The EULA in this case is just as valid as Microsoft's EULA. If you disagree with the EULA that comes with Mac OS X you may take your brand new shiny box to an Apple store and get a refund.
Psystar is selling illegal versions of Mac OS X that have been modified to run on standard off the shelf hardware. Which is essentially copyright infringement, which is one of the many things that Apple is currently suing Psystar for.
Ask a lawyer what your rights are within the EULA and you will find that the legality is not up in the air, it is rather clear and straight forward.
