Amazon discounted the MacBook Air to $1744 (after $50 rebate) today. The MacBook Air has been in Amazon’s Best selling electronics page since its release (it currently is at #17) so the markdown is obviously not because of slow sales. It is the lowest price we could find anywhere.
Amazon is also offering large discounts on the last generation Apple MacBooks ($919 after $75 rebate) and Macbook Pros ($1544 after $150 rebate). Since the latest changes were fairly minimal (in fact the older model Prros have MORE L2 Cache 4Mb vs 3Mb), it might be a good time to pick up a very slightly outdated machine at a very significant discount. Rebates end March 11.
