As the title suggest I just bought the last gen 13" macbook pro brand new sealed in the box for $800. I'm wondering if I should keep it or re-sell it and get the current macbook pro.. I figure I could get maybe my money back (800) or even 900-1000 on craigslist.. I don't hardcore game, nor really play any games. I use it to play music, and i have a 22" samsung LCD that I use as a primary monitor when i'm at home.. I was going to upgrade the HD (65$ for a wd blue 500gb 5400rpm after discounts) and the ram to 4gb (another 100$).. so in total it cost me about ~1k$ for 4gb ram and bigger HD.. which I would get on the new macbook pro anyways, for 1200$.. suggestions?
