Standard contents included. You have to fork over $80 to get the fancy new headphones with the volume control.
We're working on the disassembly now.
By the way, we'd like to congratulate Apple on their environmental progress. The one aspect they forget to mention is ease of repair to ensure reuse. Fortunately, we've got you covered there.
We'll be making a Fixit Guide for the new Nano soon. Stay tuned!

Edit Step 8 ¶
Unfortunately, just like every other Nano, this iPod wasn't designed with serviceability in mind. Sliding the insides out of the casing proved quite difficult.
We'll be working on finding a better way to get into this iPod, but for now we'd recommend keeping your new Nano in one piece.
slide the insides out until the very lowest connector is visible, about 1/4 of an inch. Be sure to undo this connector before sliding the inides out as seen in the picture.

Edit Step 9 ¶
Removing the LCD.
One of the most exciting features of the new Nano is what covers the LCD: real glass.
Earlier iPod Nanos have been incredibly durable. Hopefully, the same will be true of this iPod, even with a glass screen covering. We certainly appreciate the addition of real glass; it's nice to see some of the enhancements from Apple's larger and more expensive devices make it to the Nano.

Edit Step 10 ¶
Fortunately, the glass is separate from the casing. In fact, nothing but the iPod's internals hold the glass in place on the casing.
The front of the glass is curved to match the front of the iPod. The glass is about .7 mm thick on the edges, and 1.7 mm thick in the middle.
The new LCD is actually almost exactly the same size as the 3rd Gen Nano LCD. The only difference is that instead of a resolution of 320x240, you now get 240x320.

Edit Step 12 ¶
The top of the logic board. We're working on identifying the chips.
