Mobiles and gadgets

The iPod Touch (trademarked and marketed as iPod touch) is a portable media player, personal digital assistant, and Wi-Fi mobile platform designed and marketed by Apple Inc. The product was launched on September 5, 2007, at an event called The Beat Goes On.[4] The iPod Touch adds the multi-touch graphical user interface to the iPod line. It is the first iPod with wireless access to the iTunes Store, and also has access to Apple's App Store, enabling content to be purchased and downloaded directly on the device. Apple has sold 20 million iPod Touch units as of September 2009.[5]
The iPod Touch is currently in its third generation (3G), which is available with 32, or 64 GB of flash memory. The 8 GB second generation (2G) model is also available. The second generation iPod Touch, featuring external volume controls, a built-in speaker, a contoured back, built-in Nike+, Bluetooth support, and the ability to connect a microphone, was unveiled on September 9, 2008, at the "Let's Rock" keynote presentation. The third generation iPod Touch with the new iPhone OS 3.1 was announced and subsequently released on September 9, 2009. The third generation includes faster hardware (the same microprocessors, graphics engine and RAM as the iPhone 3GS), Voice Control and bundled earphones with a remote and microphone. The new generation and the concurrently available second generation 8 GB model are available at a new lower pricing structure.
