1) Would you recommend Bubying OS.X 10.5 used off sites like Ebay and Amazon? I brought my MBP 10.4 used and it didn't come with a disc to reinstall the software. 2) Is there a way of getting an official 10.4 disc from Apple and not pay the full price? I would much rather update 10.4 w/ my new HDD than spend $100+ for Leopard and the new version come out in the summer. 3) Does the genius folks at apple install HDD & Ram for free or is their a charge? LOL I'm a broke college kid and I'm trying to get as much bang for my buck as possible!!! Thanks folks!
