Since I got a new 2017 Air from home insurance (spilled beer...) I wanted to know what my mid 13" 2012 Air is worth on the market (works perfectly except for 4 keys not working) and was stunned by the asking prices in Canada: from $600 to $700 on average! Really? For a 2012 13"? Looked at eBay Canada and prices are about the same.And about the same on eBay US also. So after 4 years the Air is still worth... 50%? I wouldn't have thought....
