Apple's new iPod touch is the thinnest yet, at just 6.1mm. It's also the most expensive. Here's what else you need to know about the new device.
Apple fifth-gen iPod touch
iPod touch: screen
If you can't upgrade to the iPhone 5, the iPod touch gives you the chance to get the same 4-inch screen with a resolution of 1136 x 640. This 16:9 aspect ratio is perfect for the iPod touch as it makes it better suited to watching videos. See also: iPhone 5 review
As with the iPhone 5, the touch-sensitive layer is gone and now integrated into the screen itself, making the display thinner than ever before.
iPod touch: design
The 2012 iPod touch is the first to use the same aluminium housing as the MacBook. This one-piece machined casing makes it both thin and strong, and it's anodised in five colours: black, grey, pink, yellow (more of a mustard colour really) and blue.
At the bottom is a button for attaching the new wrist loop, presumably to help you keep hold of the barely-there device and prevent it slipping through your fingers.
At the top is a 5Mp rear camera (likely to be the same as in the new iPad), which is capable of shooting video at 1080p. There's an LED flash and a rear microphone to improve audio in videos.
It supports the new sweep panorama feature along with the iPhone 5, HDR, face detection, and has video stabilisation.
To the right of the camera is a black oval: this is to improve the Wi-Fi and Bluetooth signal.
Like the iPhone, there's a power button on top, a Home button on the screen, and volume buttons on the left.
The new iPod Touch also gets Apple's new Lightning connector, and a bottom-mounted headphone jack.
iPod touch: wireless and sensors
Yet more iPhone 5 features have made it into the latest iPod touch. There's dual-band Wi-Fi, so it operates on both 2.4GHz and 5GHz. You also get Bluetooth 4.0, Nike+ support, and location-based Maps (no GPS receiver, though: it uses Wi-Fi).
In terms of sensors, it includes a three-axis gyroscope and an accelerometer, but it loses the ambient light sensor of the fourth-generation iPod touch.
iPod touch: processor
Borrowing from the iPhone 4S, the new iPod touch has the same dual-core A5 processor. That's a considerable upgrade on the A4 chip used in the fourth-generation iPod touch, both in general computing power and also graphics grunt.
iPod touch: iOS 6
As you'd expect, the iPod touch ships with iOS 6, and is the first touch to feature Siri. It also gets turn-by-turn navigation and the new Flyover feature in Maps. Plus, it supports AirPlay Mirroring. This allows you to watch what's on your iPod touch on your HD TV, via an Apple TV. Photos, videos and games can be played wirelessly on your large-screen TV.
iPod touch: capacities and price
There are just two capacities to choose between: 32GB and 64GB. The former costs £249 inc VAT, while the 64GB model costs a whopping £329 inc VAT.
Both are available in all five colours, and come with Apple's new EarPod earphones. If you want to use an existing iPod dock, you'll need to buy the £25 Lightning-to-30-pin adaptor.
You can pre-order the fifth-generation iPod touch at the same time as the iPhone 5, on 14th September.
