A mobile device from Apple that combines wireless Internet connectivity with the company's ubiquitous iPod music player functionality. The iPod touch shares many similarities with the Apple iPhone, with two major differences – the iPod touch lacks the iPhone's mobile phone capabilities, and it's significantly slimmer than the iPhone as a result.
Now in its fourth generation, the iPod touch also shares the same mobile operating system as the iPhone, Apple's iOS (currently in version iOS 5). The iPod touch devices also feature support for Apple's free iCloud and iMessage services as well as all of the Apple App Store apps available for the iPhone.
Apple is expected to release a fifth generation of the iPod touch at some point in 2012, and the new device is expected to have features similar to the iPhone 5, including a larger screen and a faster processor.
