Ordered the 2GB black nano (perfect capacity - for me anyway) Monday evening (Sep 12) at 10:00pm CST on www.apple.com. It shipped Wednesday (Sep 14) via FedEx (standard free shipping) from Chenzen, China (must be where they are made). Came via FedEx this morning, Friday (Sep 16) at 9:30am CST. All I can say is WOW - very, very fast for a product that had to be customized with the free laser engraving Apple provides.
I am extremely impressed with the easiness to order, the shipping time, and updates on shipping at Apple's website (so I could track at FedEx and not miss the thing!), and of course, the nano itself - what a beautiful piece of engineering this is. As Campbell's soup afficianados say, "MMMmm Good".
