Hello, I had recently purchased a MacBook Pro Retina 13" with a 256gb SSD; After tax, and with the education discount, it had totaled out to be $1489. Later I came to find that B&H Photo is selling the older version MacBook Pro Retina 15" for $1599 (no tax). From what I can gather, these have the same display, thickness, 256gb SSD, and 8gb RAM. However, for $110 more I could upgrade to a 15" screen with a quad-core i7 CPU. Am I missing something here? I am tempted to return my rMBP to the Apple store and purchase the 15" model from B&H.
