Different laws, and U.S. precedent is not applicable.
Having looked at German law, I don't think PearPC could win, but they have a better shot than did Psystar.
1) EULAs in standard boxed software are not applicable by German law. That's why Microsoft lost its OEM law suit in Germany. Same goes to so called "hardware clauses" like Apple has them in their EULA. HP lost such a case in the 90s.
2) Psystar and PearC is a complete different story.
Psystar sold modified MacOS X discs.
PearC does sell two completely seperate products:
1) A standard PC with support for all EFI operating systems
2) The iLife/Snow Leopard set (also known as the 'Hackintosh starter kit') which they get from a German distributor (Ingram)
You can either buy one of these products or both of them. But they are compeletly different products and not connected together.
Of course the user can always choose to Install the EFI OS MacOS
3) Who says Apple hasn't already tried and lost? Court decisions don't get published in Germany...
