2nd gen as above. No scratches. I bought it about 18-months ago directly from the Apple store here in Reno with a 2-year extended warranty (I don't know if the warranty is transferrable or not). But back in May of this year it locked up and even Apple couldn't fix it so they replaced it under the warranty; so really its only 6-months old.
Its always been in the silicone cover (NOT included) so it is like new: No scratches visible. I have the original box.
Its a great device and as I said I wouldn't even consider selling it except I need the additional capacity of the 64Gb model.
