I was looking for one of the new Macbook Air's for my GF's son for school next year. This struck me as an excellent deal for local stock from an Authorised Apple reseller.
Looks to be available in all 3 colours (Grey, Silver, Gold)
Specs on the configurations and colours on Apple's site here
Personally think that the 256GB upgrade is a bit of a rip off but hey, that's Apple for you.
Don't forget your preferred Cashback/Qantas referral option for a few dollars back/points.
EDIT: Looks like my calculator had an aneurysm when I first worked out 15% off $1699. I've fixed with the correct price of the 128GB model, 256GB was already correct.
Littlest miss entropy extremely happy with her gold MBA 256 GB bought around this price a couple of months ago.
