There's not a lot to discuss here. While I've been almost (but not quite...) an Apple Fanboy for the last decade I do hate what's happening. I'm a mere programmer, and I cannot understand if this could seriously harm Apple lawsuit, but if someone can please tell so!
Obvious question: how could a court tell it was actually prior, other than to take his word for it? Seems useless without proper proof that he didn't write the code yesterday.
(sorry for my horrible english...)
