Eh. I sold off the 2008 (first version, first day) Air for $350 a couple weeks ago, after finally pulling it off the shelf and repairing the keyboard cable. It can't even be upgraded past Lion. Poor resale value is relative. Given how limited that machine was, it still stuns me that anyone was willing to pay virtually anything for it. The bizarrely high resale value of older, undesirable models sets a fairly high floor for these things no matter how much better V2 is.
That said, just as with cars, you rarely get much credit for options. If you are thinking in terms of resale, you are generally best off going with the fewest options possible.
