Folks, Soon will be very new to the mac family as I'm considering waiting until the refresh of the 2012 Macbook Air. Unfortunately, I'll need to buy one by the middle of June for a trip In taking. I want to use it download hundreds of photos I'll take on my vacation. I could wait even longer and use my netbook, but that's a painful experience to say the least. How much, if any, do you expect the spec bump to be on the new air, and will it come out in time for my mid-June need. From my readings, I think it will not and I'll be stuck with the 2011 model. I'm also considering a refurb unit to save some $$$.
