hi fellow mac users! i just wanted to ask whether buying a 1GB ram for my powerbook is a good investment? i currently only have 256MB. i only use my PB for school n enteratainment purposes (movies, internet,etc). i think that OWC has a good deal with the 512MB but i want to maximize the 1 slot provided by the powerbook. will the 512MB be sufficient? will there be a significant price drop within the next month or so for the 1GB sticks? i also saw a 1GB stick being sold in outpost.com for $179. was just wondering if you can give me advice, i really dont want to spend too much money on ram since i'm low in funds heheh. thanks!
