Ok... I got my first Mac. It was given to me for doing some computer work for a friend. It just needs an LCD which I already ordered. It came with 512ddr on board and I want to add 1gig. According to the manual I read on Apples web site I need DDR SO-DIMM and it is good at pc2700. Is that really all there is to it? Do I just go to a computer store and buy pc2700 DDR SO-DIMM memory for a laptop? It does say in the manual about it being no bigger than 1.25" Some help here with my first Mac would be great. I am hoping for a good experience so I move add Mac to my Ubuntu repertoire. Thanks in advance!
