I know there are plenty of other upgrade options and so on, but of these two specific models, which would you rather buy? Both work out to be almost the exact same cost if you factor in the student pricing on the 2012 model along with the $100 iTunes card and Discover 5% cash back (both come to a net of $866) 2011 11" MBA (refurb) i5 1.6 GHz / 4GB RAM / 128 GB SSD 2012 11" MBA (new) i5 1.7 GHz / 4GB RAM / 64 GB SSD Basically a trade off of processor speed for storage space. I only use about 40gb of space currently though. Also USB3 and HD4000 in the newer machine. Thanks!
