I local Apple reseller has a used 11" Macbook Air 1.6 i5, 4gb, 128gb for $899. I was going to wait out the new ones, but 25% off the retail value seems like a great deal. It is mostly meant to be my secondary computer since I built a Hackintosh and sold my 2011 mini for $800. Is a 25% discount worth buying in, even with a new model probably coming in the near(er) future? Thanks for any advice.
