Hello! I'm interested in purchasing a 13'' Macbook Air 256 GB 1.8 ghz. I am wondering if I should wait or buy now...yes, I know this type of thread is a regular occurrence, but there's a catch. I can wait if need be, but I am trying to stretch my dollar. One can currently purchase a refurbished Macbook Air 256 1.8 through Apple for less than $1,500. If I were to wait and buy the 2012 version, would the economically comparable model (presumably the mid tier 13'' version) be comparable in power and long term viability to this 1.8 machine? Of course no one really knows the cost structure of the new Airs, so I have a few specific questions to help narrow this down: 1. Have SSD prices fallen? Is it expected the cost of the SSD storage to be less for the new Airs? 2. What is the power equivalent of the Ivy Bridge processors? I really know little about processor speed. Assuming 1.8 is the top speed for the current Air, how much faster would the mid tier model be expected? 3. Graphics speed is expected to be faster, but is this expected to be a noticeable bump? I view CADS (don't create) and do play some 3D games, but gaming isn't a major concern. Would I expect to see a big boost for the mid level Air over the top tier Air vis a vis graphics capability? Am I missing anything? Basically, I am trying to figure out if economically it makes sense to wait and buy a mid tier model or buy a discounted high end model. I engage in basic computing activities (web, e-mail, music) and some more advanced activities (CAD viewing, light gaming).
