under _german law_ it's different i'm sorry ... for retail boxes license agreements inside of the box not visible at the point of sale are null and void (difference between downloadable software where they might be presented before buying)
and even if the whole EULA was printed on the box (impossible) it would have to adhere to the BGB rules about AGBs which are very strict and limiting
_if_ the Apple EULA is valid as an AGB then it could be very easily argued that the restriction of the "software installation/usage only to be allowed on apple branded computers" might break with §307 of the BGB since it is restricting the enduser onesided and thus would make the AGB invalid and then the german "Erschöpfungsgrundsatz" comes to play ...
go to the top of the thread and read the "german" part again (thus your Dr. Zoidberg case is not applicable here)
wether or not those Pears are "unlauterer Wettbewerb" is another ballgame but it looks like quite a thin case to me .. but since Gravenreuth has finally be convicted everything is possible now
