OK, I know there are tons of threads about this, but I was just wondering if you all think I should upgrade my RAM. I have a brand new 2.2GHz Black MacBook. I don't do video editing, photo editing, nor am I a gamer. At times, my RAM gets up to 70% in use, but I have never seen it higher then that. Since I am not an editor or gamer, would I notice a difference at all between the 2GB I have right now or 4GB I could get from OWC or Crucial? I am all for speed, and just sold my MacMini, so I have some extra cash to spend. I am planning on setting up my area so that I run my macbook closed when I am at home, using an external monitor, and obviously portable when in classes. Would the RAM help me out at all, or is there something else I should spend the money on instead, like a good case and marware protector stuff? Do the blackbooks really need a marware protector? Thanks!
