Bought a new, 8gb RAM, 256gb HD, Air 13 from Best Buy yesterday for $999. One day sale, I think. Heck of a deal. Got home and plugged in the serial number on Apple's website and found out the build date on my new Air is "Early 2015." Kinda bummed me out. Looks like Best Buy sold me a computer that's already 1.5 years old. Guess it's been sitting in a warehouse somewhere for a while. Anyway, I figured with the "new" 8gb standard memory for 2016, I'd get an Air with a build date of "Early 2016." So now I have a dilemma. Should I keep the computer and not worry about it? Or should I exchange it for another one and hope for a later build date? Or, are they all going to have a build date of Early 2015? What happens when I go to sell it someday, will the build date affect what I can get for it? Love to get some opinions on this situation. Thanks!
