Hi, I think I really want a white 2.2GHz Macbook. I have look on several seemingly legit websites and have found 2 sticks of 2GB memory for this computer for about 115 bucks. Is there a downside to having more RAM? Where should I be getting RAM for a Macbook? In theory, could I just get the 2.2GHz Macbook with only 1GB of memory, then remove the 1GB and put in the two new 2GBs? Is installing the RAM easy or do I need to take it to a store? Any information is greatly appreciated.
