IPod Touch

The iPod touch is a multi-purpose pocket computer designed and marketed by Apple Inc. with a touchscreen-based user interface. It can be used as a music and video player, digital camera, handheld game device, and personal digital assistant. It connects to the Internet through Wi-Fi base stations and is therefore not a smartphone, though its design and operating system are very similar to Apple's iPhone. As of May 2013, 100 million iPod Touch units have been sold.

As a consumer electronics device, the iPod touch is sold using a deliberately simple generation system. All models of a generation normally have identical features, processors, performance and available operating system upgrades, differing only in outer color and internal storage space. An exception is the currently available fifth generation, as the low-end (16 GB) model is sold without a rear-facing iSight camera for taking photographs, and lacks the iPod Touch loop.

There are five generations of iPod touch, of which between the 2nd and 5th editions there are not many people bought iPod touch.
