Wannabe Mac cloners Psystar hired itself some hotshot lawyers to defend against Apple's lawsuit, and they're not wasting any time earning their fees -- as Psystar's hinted in the past, it's going to countersue Apple for antitrust violations and ask that the court declare the Leopard EULA void. That's a pretty longshot argument, especially since EULAs have traditionally been upheld in California and Florida and we find it hard to believe a court would find a company with ten percent marketshare to be abusing a monopoly position, but we'll see how everything goes down -- this one is going to have some fireworks for sure.
