Hi, The 13" MBP comes with two GB of RAM. I currently own an ibook, but I am gearing towards using several design and audio applications. I wonder if I'll really need some extra RAM. If I do it, I would get four GB, and not eight GB (pricey!!). I just wonder what kind of work will i be doing in order to need four GB of RAM, as opposed to two GB ?? Thank you very much in advance, very kind regards, igmolinav.
