Hey, I was just wondering about how future proof both the Macbook and the Macbook Pro are. We all know that the Macbook Pro can be upgraded to as high as 4 gbs of RAM, which would last anyone a really long time. But what about the Macbook? Is it future proof enough with just 2gbs (I believe it can go up to 3?) as we all know in the future, newer versions of OS Xand other computer applications are going to require more and more memory. This will really be a deciding factor for me, as I want to have a computer that is going to last me way into the future. Thanks guys.
