Hey-ya, I have a 12" PowerBook 1.33Ghz that currently has 768MB of RAM. I'm thinking of replacing my 512 stick with a 1GB stick for a total of 1.25GB of RAM. Now my question is: would it be worth the expense? I'm really looking for performance increase in MS Office (particularly Word) and maybe other apps like iTunes, Firefox, but not much else. A full system upgrade is a ways away for me but thought this might be a nice stop-gap. Word in particular really bogs down when I have a large file open to work on. Any comments or suggestions? Thanks!
