Mac models come and Mac models go. A fairly sure sign that the MacBook Air is about to be updated is that Apple has cut the price of the refurbished units. And, yes, they come with the usual trimmings — free shipping, free (after rebate) printer, new battery (portables) and a full + extendible AppleCare warranty.

Is it twu what people are saying about refurbished MacBook Air pwices? It’s twu! It’s twu! Apple has cut their asking price by $20 for the entry-level model. I’ve tossed in a few other of Apple’s current refurbished offerings for comparison’s sake.
