That is corporate code for we screwed up, and estimate eating the difference between a new and refurb unit is cheaper than the potential business lost if during the prime back to school and run up to christmas shopping season, we have someone running around talking about their Apple product that slipped through the cracks at some depot.
Honestly, you probably got a system that got put into the wrong pile. Someone was probably trying to do one too many things at a time, and that system got sent out with the completed units instead of staying with the "work in progress" systems. Might have been the end of the day Friday, and they figured they'd just restore the OS now instead of wait until later. Monday comes along, they see the system sitting there with the OS having just been restored, figure it's ready to go out with some of the rest, completely forgetting that it still needs at least a new display... And the rest is history.
Let he, or she, who has never set something down on Friday and forgotten all about it come Monday, be the first to cast a stone.
BTW, congrats on the new laptop. Can't ask for much better result than that. New for the price of refurb.
