This weekend I am goign to an Apple Store and I;ve decided I want to purchase a new Macbook. I am buying the white model with superdrive and 1gb of ram. I am definately planning to upgrade the ram as soon as I get it. My question though is, do any of you think its worth it to get 4GB of ram or should i stick with buying a 2GB stick and leaving one if the originals in for a total of 2.5GB? I used to own a powerbook G4 12" and it had 640gb of ram and at the time i felt it was quite limiting. My general use of the laptop will be office '08, i'll be using parallels with XP or vista(havn't decided yet), I use photoshop from time to time, ecode movies, used imovie sometimes... For this kind of general use, do you think i should jsut go ahead and buy two 2gb sticks, will it make a difference for me? I havn;t used leo yet and I'm not familiar with how many resources it uses. I like my computer to respond well all the time and i'm nto very patient for when physical ram is used up. This is mostly a question to those of you who have 2gb and wish you had more. I was also curious, does loosing dual-channel really make that much a difference as well?
