I would even consider the 13 MBA if they offered an i7 configuration. It feels like that was purposefully omitted in order to push buyers towards the Pro.
I hope that both the macbook and new Airs take a similar trajectory to the original Airs. The first iterations (2008-10) were quite weak performance-wise, it was more about Apple planting a flag and saying "this is what the future laptop will look at" and iterating under the hood till they reached it.
After buying a pro and returning it, then seriously eye'ing the new airs, I've fallen back to...buying a new battery for my old 11 Air.
