Psystar, prominent makers of "Hackintosh" PCs running Mac OS X, is set to respond to Apple's copyright infringement suit on Tuesday and file a countersuit of their own, just like we thought. Psystar owner Rudy Pedraza insists that his OpenComputer hardware is merely "providing an alternative, an option" to Apple's pricey hardware. Pedraza plans to countersue Apple under two federal antitrust laws, hoping to prove that Apple's fierce tethering of OS to hardware represents an "anticompetitive restraint of trade." It'll be an uphill battle to fight Apple's legal team, but I kind of hope they win: it's like David versus Goliath, if David and Goliath were both big nerds. [CNET]
