I currently own a White 2.16GHz Macbook with 1 GB of Ram. However, after downing iStates it became pretty clear that 1 GB of Ram isn't going to cut it if I plan on running Windows XP via Parrallels along with iTunes, Adium, Word, and Safari at the same time. Does anybody have a suggestion as to a good, relatively cheap 1 GB Ram card I can buy in order to update my Ram? The card will need to be Apple approved so that it doesn't cancel out my Warrenty. I heard that upgrading the Ram yourself is cheaper than buying it from Apple, since it cost $160 to upgrade your Ram on Apple, I am assuming it will cost about $100ish?
