I have a friend who is going to purchase a macbook pro for me in exchange for some web design. This will be my first mac computer. He's willing to get a refurbished 2.5 i5 (2012) from Apple at $999. I was looking through Amazon and we can get a refurbished 2.7 i7 for $850. http://www.amazon.com/gp/offer-list...olp_refurbished?ie=UTF8&condition=refurbished What am I missing here? Isn't an i7 better than an i5? What's the deal with the price discrepancy? Please forgive the question if the answer is obvious. I'm in the middle of my divorce from Microsoft.
