So after a lot of thinking and reading I have decided I will buy a 13" mbp to take with me to college this fall. I just wanted to make sure I have everything straight before I invest my money. I am going 2.4 processor because I read the upgrade is not worth the money. Correct? It comes with 250 gb hd. I was thinking about getting the 320 gb hd. Should I do the upgrade when i buy the mbp, or should I replace it myself? I am going to get 4 gb of ram. If I find I would like more I will upgrade later. Will it be cheaper to buy ram from other dealers? I can also purchase the AppleCare off ebay for cheaper right? Is there anything else I might need? Thank you in advance!
