When a Mac is sold, the warranty clock starts and is tied to that serial number. If they took it back and resold it as new, the new buyer would get less than 1 year warranty coverage. Refurb models are given a new serial number that identifies them as refurbs, and also allows for the warranty clock to start again when they are sold. You can verify remaining warranty/AppleCare coverage for any Mac by entering the serial number

Apple refurbished products are considered by most to be a very good deal, as they're pretty much like buying a new Mac, except for the box.
