I bought my new 2015 11" 4/256 MBA from an Apple Store 11 days ago for $1112 after the $50 education discount. Apple is selling the 2013 11" 4/256 MBA for $809 ($857 after taxes). I just use my MBA for pretty much internet browsing, music, and movies. I'm within my 14 day return period so should I return my 2015 MBA and buy the refurb one saving me $255 or is the new Broadwell chip worth it? I got my mom the 2013 refurb and I don't notice any difference with it compared to my 2015 one.
