So I went to FRYS yesterday and got the 529 bas 2.3 i5 deal. Upgraded to 8gb of ram by PNY from BESTBUY. I think it was apple (I don't remember) saying lion needs 4gb minimum ram and is hungry. Well my 2gb stock was runnig out super fast so 8gb was badly needed. Anyhow few question. Is mountain lion more memory efficient like going from vista to 7. Or mountain lion is also memory hungry. And what is the minimum. Would 2gb have sufficed if I never upgraded. And everyone keeps saying the mountains will be filled with lions tomorrow. How do you know its tomorrow if it doesn't even officially say on their website. Were are you getting tomorrow from. Also I forget what the apple guy said. How do I upgrade for free. He said any computer bought after the 11th of july. But where do I register for the free coupon. Thanks for the advice.
