I was thinking about buying the Black MacBook, stock edition and upgrading the RAM. Is this RAM good and compatible? http://macrumors.pricegrabber.com/search_techspecs_full.php/masterid=18349260 I was going to buy two of them and max it out to 2 GBs. If not can you suggest some compatible, easy to install RAM for the macbook, cheap as possible. Thanks.
