Set condition one for bargain hunters! The U.S. Apple Store is now offering refurbished MacBook Air models with 1.6GHz processors, 2GB of memory, and 80GB (non-solid-state) hard drives for $1,549. That's a savings of 14 percent from the retail model. Or, think of it as getting a free AppleCare subscription (for $249). As of this writing, the refurb model shows shipping times of three to five business days. Thanks, Chris!
