There's a thick slab of glass covering the LCD. Unlike the iPhone, we haven't seen issues with broken glass on the nanos.

If you want your screen to look nice, don't touch it. Fingerprints are quite noticeable on the glass.

Removing the internals... It's a tight squeeze, but we got them out. Getting this iPod open wasn't easy. We don't recommend trying this at home.

We wish Apple would put a little effort into making iPods repairable, instead of forcing people to throw them away when they break. Recent iPods have become increasingly difficult to successfully repair.

This iPod employs copious amounts of glue and adhesive to hold everything together. That makes it easy for Apple to put together, but hard to take apart.

The tolerances on this iPod are incredibly tight, there's no wasted space inside.

The new nano features a larger display (2.2" and 240x376). This is the same width as the 4th Generation nano, but 56 pixels taller. On a pixel basis, that's 17.5% more screen real estate.

Apple keeps putting bigger screens in the same size devices. The footprint of the iPod nano has stayed the same over the last four years, but this display has four times the pixels of the original nano.

The battery. Apple warns you right from the get-go that your iPod may melt and/or spontaneously combust: "Potential for fire or buring." We assume they mean burning. It is assembled in China, so we'll give them a little slack.

Supposedly if you burn this battery, it will burn.

It's readily apparent the battery has not changed much. Just compare it to the battery of yesteryear...

Here's the speaker. Like the Touch 2nd Gen, the audio simply comes out the bottom of the iPod.

For something only about a millimeter thick, it's not really fair to complain about audio quality.
