Hello everyone, I am planning on getting a new MacBook. I currently have a early 2015 8/256 MBA, and my wife has a mid 2013 MBA 8/256. Currently Gazelle is offering $440 (good condition, $485 for flawless) for the 2015, and $307 (good condition, $345 flawless) for the 2013. If I sold the 2013, I'd give my wife the 2015. If I sold the 2015, my wife would keep the 2013 (she doesn't really care or want a new computer). I suspect the spec/performance differences between the two computers are relatively small, wasn't sure if there was some other "improvement" that I wasn't aware of that would make a stronger case for keeping one over the other. Welcome your thoughts!
