Your zeal to provide assistance is appreciated, but the additional information was superfluous to the point that it knocked this thread off track. We would all have been better off if you'd simply suggested calling Apple.
I did suggest calling Apple in my very first post. You simply focused on the extra piece of information I provided rather than reading the whole post. The extra information about checking the serial number for the specs was not superfluous, but a way of determining if the specifications were the same. That would be useful even if the replacement was not a refurbished model.
The whole discussion is rather pointless, as there is no difference between a refurbished model and a new model, except for the possible presence of very minor cosmetic details.
