The iPod Touch, first introduced in 2007, featured a multi-touch display that only sensed a human's touch. It also featured the iPhone OS. (Known today as iOS). Today, the iPod touch comes in two colors - White, and Black. The current iPod Touch features a multitouch display, dual cameras in the front and back, iOS 5, a gyroscope, ambient light sensor, as well as the most advanced hardware specifications ever built into a mobile device, (excluding the iPhone 4, iPhone 4S, and the iPad 2) more or less an MP3 player. And coupled with iOS 5, it makes a perfect utility for anyone.
