So I recently went the Apple's refurbished site and got this: http://store.apple.com/us/product/F...-23ghz-Quad-core-Intel-i7-with-retina-Display The Macbook Pro 15 inch with Nvidia graphics card. They also had this: http://store.apple.com/us/product/F...-20ghz-quad-core-intel-i7-with-retina-display Macbook Pro 15 inch with Intel Iris Pro graphics. I got the first one but now I'm thinking if I should have gotten the 2nd one. The only difference is the graphics. I had a Macbook Air 13 2012 before I spilled coffee on it and ruined it. Should I just get a Macbook Air 13 2013 which is 799, 1/2 off the price of the Macbook Pro 15 inch and stick with that? I was happy with my Macbook Air before the incident. Thanks.
