Conventional wisdom seemed to dictate that as soon as Apple filed a lawsuit against Psystar, Psystar was going to start sneezing hemoglobin and teeth. But Psystar's being surprisingly resilient. They've just hired an attorney, and it doesn't appear to be some bargain-basement defender. They got a good one.
The firm they've hired is Carr & Ferrell, who specialize in intellectual property cases. A few years back, they successfully fought Apple off in the Burst.com case, and Apple was forced to settle and pay them $10 million in fees.
In short, Psystar has hired an attorney with a proven track record of beating Apple in court in intellectual property cases. I've been hoping against hope that Psystar had some sort of plan here, and it appears they did indeed. It always looked like Psystar wanted to get sued by Apple, but the more obvious answer was corporate doofusism, as opposed to a conspiracy to test Apple's EULAs and copyright claims in court. Maybe Psystar is as wily as we hoped.
