Among the changes to the iPod touch, which will ship with iOS 6:
- A larger 4-inch Retina display with a 16:9 aspect ratio, the same used in the new iPhone 5.
- The new iPod touch is just 6.1mm thick and weighs only 88 grams. This makes it the thinnest and lightest iPod touch yet.
- The fifth-generation iPod touch is getting a processor upgrade, unlike its predecessor. It does not get the A6 though, but the iPhone 4S' A5.
- The iPod touch 5G will also have access to Siri
- Battery improvements will give users up to 40 hours of use when listening to music.
- The rear-facing iSight camera has been upgraded to 5-megapixels with an LED flash, backside illumination, and more.
- The front-facing FaceTime camera - as with the iPhone 5 - now records 720p video.
- There a long-requested chassis loop added to the iPod touch 5G, too, which can be used for lanyards (and in a somewhat snarky manner, Apple is calling it the Loop).
- Bluetooth 4.0, 802.11 a/b/g/n, and support for AirPlay mirroring are all supported.
- The new iPod touch comes in five colors (pink, yellow, blue, white, silver, black, and slate). The Loop will be color-matched to the device.
Last year's model will continue to be sold as a lower-cost entry. Just as with the iPod touch 5G, the continuing 4G model will ship with iOS 6. It will come with 16GB for $199 and 32GB for $249.
