Even if someone cracked OS X for the PS3, it will not work well at all. The cell processor's PPE performs worse than a single core 1.6GHz G5. Why? To lower costs, IBM disabled out of order execuction. And seeing as how OS X wouldn't even touch the SPEs, you are left with a fairly weak machine. To top it off, 200 mb of ram? I say 200 because from what I've seen, that is how much is available to other OS, not 256 (I may be wrong.)
Simply put, the PS3 can't handle it.
Never argue with an idiot. They drag you down to their level then defeat you with experience.
