Thinking seriously about buying a MacBook Air, however I am concerned about not buying one with enough memory. How is the resale market for such devices if my sole reason for resale is to repurchase with a larger hard drive. I know in typical Apple fashion determine what you need prior to purchase but their additional cost for storage is ridiculous.

Basically I am thinking of buying the 256 or 512GB model and hoping that is enough memory (I do not use remote / cloud storage) If I end up wanting more storage than that I might as well go with the MacBook Pro. If I were to turn around and sell in the current market what percentage of the original retail are you likely able to recover presuming it is in as new condition after restoring to factory defaults and wiping the drive.

I know its a purely speculative opinion but am curious.

As far as my windows based daily driver that this laptop would supplement, my iTunes library alone is 760GB and If I do not want to put the entire library on a laptop I think I could get away with the 512GB Model.
