I have just upgraded my Powerbook 667 to 768mb from 512mb. I cannot describe how easy this process was! Just remove the keyboard, push the two side levers to eject the memory module, slide in the new memory module and *presto* you are done (less than 10 seconds)! The system detected the upgrade immediately and i was on my way typing notes in class. I have yet to notice any improvements but I am certain this will be evident when i fire up high memory applications (esp. Photoshop) or when running several demanding applications at the same time (Words, Powerpoint, iTunes, Camino besides numerous background applications :P). Now, I have a spare 256mb memory module. I was wondering if any of you are interested in upgrading your Powerbook's memory (esp. if you are still surviving with 256mb of RAM). I am willing to sell this memory module for $20 plus shipping. For those who are interested, please email me off-list. Thanks, JranDe Lee __________________________________ Do you Yahoo!? Yahoo!
