Removing the internals. There's a single connector that attaches the logic board and battery to the rest of the iPod.

The form factor of this iPod shares more similarities with the original iPod Shuffle than its immediate predecessor.

It's in three pieces now. There are not many parts in this iPod.

This is not a surprise, but like all other Shuffles, the battery is soldered to the logic board. Apple does offer a battery replacement service, but $49 is pretty steep considering the entire iPod was only $79.

The headphone jack and shuffle switch come out as one unit.

The back of the casing is stamped 09/03/03. If that means March 3rd of 2009, then this Shuffle has been assembled for no more than nine days.

In the third picture, you can see the white translucent piece of plastic to the left of the headphone jack. This serves to transmit the the LED status light to the outside of the iPod.

Apple's claimed battery life on this iPod is 10 hours. That's two hours less than the previous Shuffles.

The 3.7 volt lithium-polymer battery lists a capacity of 0.27 watt-hours.

To calculate the capacity in amp-hours, we know P(power) = I(amps)*V(volts), so I = P/V. That yields a capacity of about .073 amp-hours, or 73 mAh. That's definitely record-breakingly small in terms of iPod batteries.

The primary (and only) chip, which is a multi-layered stack containing the CPU, RAM, and 4GB of flash memory. According to its markings, the chip was manufactured in week 7 (late February) of 2009.

A quick look at the innards of the earbuds' controls -- nothing too exciting.
