I no longer need the processing power/graphics from my 15" rMBP so logically thinking of getting the Macbook for better portability. Would get a MBA but that non retina screen...doh..... My purposes: general web browsing and store photos, "non power" user. Found someone willing to trade his base rMP (1.1ghz/256 gb, warranty ends July 2016) for my early 2013 15" rMBP (2.4 i7, 8gb RAM, 256GB, 1 GB VRAM GT 650M). Have Applecare until Aug 2016-one more year of warranty. My rMBP in mint condition/good battery life, etc......nothing wrong with it. The macbook will include the USB-C multiport adapter. Would this be a fair trade or should someone add more cash to the deal?
