I'm new to this forum. Hi! Anyway, I'm basically a fulltime laptop user since my desktop died, and looking to buy a new macbook. I wanted to fully upgrade the macbook since this will be my computer that should last me for at least 3 years. I've heard that I should not upgrade the ram from the apple store as it is overpriced and you can find cheap ram elsewhere. What about the harddrive? I want to upgrade the 250 to a 320gb harddrive. Would it be cheaper to invest in a different harddrive and manually install it or should I go with the apple upgrade? Not sure if its even possible to upgrade the harddrive on my own (I'm not much of a computer literate person when it comes to opening up computers) Thanks!
