I have a 2012 Retina MBP 13" with 128gb ssd that I recently acquired in a trade for an Asus gaming laptop. I have an offer to trade the rMBP for a 2012 Macbook Air 13" (4gb ram 256gb ssd, i5) AND a late 2011 13" MBP with 8gb ram and a 2.8 i7. Should I make this trade? I would probably sell the Air just because of the ram limitations and benchmarks show the 2011 MBP are on par with the 13" rMBP...but that screen is so sooo pretty. I'm new to Apple laptops but I know they all hold their values very well. This seems like a great deal for me on the sufrace but what do you guys think?
