I am doing my first pass through this thing and will offer more substantive thoughts later, but one would think that an error such as calling the Mac OS "Max OS" would not have made it through the proof-reading process. Okay, probably petty, but I laughed. It is also interesting that Psystar denies that Apple is a pioneer of the personal computer revolution! O rly? Then why are they so eager to sell its work product? Eh? Come on, denying the obvious is not a really good way to establish believability.
Update: All that being said, after a skim through the entire document, there are some very clever arguments made, and the pleading itself is well-written and thought-out. It is just unfortunate that the glaring proof-reading gaffe was on the most important word in the whole case.
