Got the other 6GBs yesterday. It was only like $95 for the memory, so why not? I didnt' expect to notice any performance gains, but they are there. Even simple stuff like scrolling through an external drive I noticed there is immediate response. Everything seems a little smoother. It was pretty fast already, don't get me wrong, but I think it was worth $95. Might save me the need to upgrade for awhile as well.
