I have the fully upgraded 15" cMBP with a 2.6 GHz i7 processor, 8 GB of RAM, 750 GB 5400 RPM, and a 1 GB 650M. A friend of mine offered to trade me his 13" rMBP with a 2.5 GHz i5 processor, 8 GB of RAM, and a 128 GB SSD. His rMBP comes with Applecare, but my cMBP has no warranty at all. Considering this is the first generation 13" rMBP, would this be a good deal for me? I'm looking for a computer to take with me to college, and my current 15" seems a bit hefty, albeit powerful.
