I don't feel a moral obligation not to steal from Apple. I'm not sure I could steal (and use) an amount from them that would impact them at all. I mean even if I stole a classroom full of MacBook pro's in order to give free programming classes - it's not like it would affect Apple in any meaningful way.
But I don't quite get why anyone would go out of their way to get hw they'll never be able to run legally licensed os on. For fun and learning, sure. Turn your linux/bsd box into a hackintosh by dual booting. But you can never do any work on it without risk. So what's the point?
Sure you can "buy" a copy of os x - but you only get install media and a license to run on Apple hw.
