What do you guys think about it? I want to have this laptop for a long time, but it would cost me an extra 180 to get 16Gb. I don't do heavy photo/video editing, but I surf on the internet with plenty of tabs and flash applications, Pages, Excel and iTunes all together. Is it worth going from 8 to 16Gb only to make it "future proof"? RAM does that much difference to justify spending that much more, or do you think I would be better off saving that money for buying a new one 4/5 years from now?
