[threepio]

I have bought Apple refurbished machines. I always understood them to be more-or-less unused returns. IIRC Apple cannot legally advertise returned machines as "new", hence the "refurbished" designation.

Moreover Apple has an essentially unlimited supply of machines. I can't imagine it would be worth it to actually take in machines and repair them (not least because it would undermine confidence in the refurb store if it was a gamble about whether you'd get a basically-new machine or beat-up machine.)
