i've decided that i need some more ram right now i have 512 that i had put in when i ordered my powerbook (lastest model). i think it is in two 256 sticks. anyway i have two questions. 1. where are the best places to buy ram for my powerbook? (i live in australia) 2. we have an oldish ibook 700mhz with 384mb, can i put my old ram in there? sorry i'm clueless.
