Hey guys, i have a macbook (2.2 SR, 1gb RAM) and was thinking of upgrading. Ive seen a lot of people put in 4gb's into their macbooks, but am not sure if i really need it. To be honest, im not sure if i need more than the 1gb i have now. So will i need the extra RAM, and how much should i put in? and is it better to go from 1 to 4gb or 1 to 2 to 4 over a long period of time. I mainly use it for general use (web, downloads, music, occasional retouching of photos, and very basic imovie stuff..athough i do plan to install windows xp on it in the near future) Thanks!
