My Dad wants an 11" air to use for a few years and I was trying to theorize which version would be the best bang-for-the-buck in terms of cost vs performance. It seems to me that the 2013 is the sweet spot assuming you buy one with 4gb and 128 or more storage. If I understand correctly, this model got the great increase in battery life due to the efficiencies with the processor and subsequent 11"s didn't get much faster, correct? That makes the 2013 worth the premium over the 2012 to me. Any thoughts here?
