Apple iPod touch 2nd Generation (32 GB) MP3 Player

The main differences:

- The 1G has a flat backplate, the one on the 2G tapers out and becomes thinner at the edges like with the iPhone 3G.
- 2G has a redesigned Wi Fi receiver cover - it's a rectangle in a corner of the 1G, but on the 2G it's more curved and moved closer to the centre of the backplate.
- The 2G is slightly (0.5mm) thicker than the 1G.
- 2G has a speaker.
- 2G has external volume controls.
- 2G is not FireWire compatible while the 1G is (that's not important unless you have any old iPod accessories that use FireWire that you want to use with the 2G)
- 2G has longer battery life.
- 2G has a better-looking screen (the 1G seems more washed out in comparison)
- 2G has Nike+iPod support.


Wi Fi receiver
- The Wi Fi receiver on the first generation iPod touch is situated in the upper left-hand corner of the backplate, and is very square-shaped.
- The receiver on the second generation touch is more of an oval shape and is situated between the upper left-hand corner and the center of the backplate.

Backplate
- The backplate on the first gen touch is rather flat, and curves only at the edges.
- The backplate on the second gen touch is tapered; it's thicker at the middle and curves around to become thinner at the edges (much like the iPhone 3G).

Thickness
- Contrary to what some people say, the second gen touch is actually 0.5mm thicker than the first gen.

Bezel
- The first gen touch has a black aluminum bezel around the screen.
- The second gen touch has a chrome bezel, like the iPhone, which is in fact a continuation of the chrome backplate that curves around to "hug" the screen.

Volume controls
- The first gen touch features no external volume controls.
- The second gen touch has volume controls on the left-hand side of the device (when looking at it from the front).

Packaging
- The first gen touch comes in a black box. "iPod touch", the Apple logo and the device's capacity are embossed on the sides. The front of the box shows the iPod touch playing music (usually the box will display either a Macy Gray or John Lennon song playing).
- The second gen touch comes in a clear plastic box, like the iPod nano and shuffle. Over the iPod is a sticker which shows the default look of the Home screen.

MISCELLANEOUS
- The second gen touch has an inbuilt speaker. The first gen does not.
- The second gen touch has Nike+iPod support, whilst the first gen does not.
- The second gen supports audio recording and headphones with a microphone and volume controls.
