I currently own the Aluminum MB 2.4, and was wondering about everyone's thoughts on which to upgrade? I have it set with the stock configuration, and have 35 GB of HDD space left. My question is, should I upgrade the RAM, and get the speed boost even though it runs relatively well, or should I upgrade the HDD to give me more space? It runs well as is, and most of the files we're things that I had accumulated throughout the years, such as video and stuff, so it is not like I need one or the other right now. I am just curious as to other people's preferences on the matter.
