It's a pretty sweet little unit, and suddenly I don't miss my old Nano as much as I thought I would. It comes by itself without anything (no original box, headphones, charger, manual, etc.). I downloaded the manual just to see if there was anything I didn't already know. It recommended charging the battery for 3 hours before first use, so that's what I did.

I hadn't even bothered to look at the 6th gen on Apple's website. I'm surprised by how much they retail for. Merry Christmas! 🙂 Two features I was surprised it had: One is FM radio (with song I.D. if the station supports it). I've been listening to the radio all day. I still have the Apple FM-radio accessory add-on for my old Nano, which is about the same size as a current iPod Shuffle, but I should be able to sell it on eBay or Craigslist easily.
I was also pleased that it has voice memo. The nice thing about having a working Nano again is I can use it for listening to music, podcasts and audiobooks instead of my iPhone. I'm often in places where I'm unable to re-charge my iPhone, so to conserve battery for phone and email, I don't use it for listening to music/podcasts.
A potentially major disappointment for some might be that the 6th gen doesn't sync your address book, calendar, notes and to-do lists. I don't know in which generation of Nano that stuff went away, but if I didn't have an iPhone, I'd be pretty crabby about that. I used those features on my Nano, like a portable organizer, for years until I got my first iPhone, but I guess I wouldn't need them now even if it was still possible.
