A Brief Overview of iPod Touch

Enter the fifth-generation iPod touch, the 2012 model that has slimmed down to a mere 6.1mm in thickness. It's also about 10 percent lighter -- despite being grafted with a new 4-inch Retina display. Not only is it bigger and thinner, but it's far faster and has hugely improved cameras on both the front and rear.

The fifth generation improves on that in every regard. As mentioned above, it now measures 6.1mm thick, while its width and height clock in at 4.86 by 2.31 inches (123.4 x 58.6mm). Compared to the fourth-generation touch, which measured 111 x 58.9 x 7.2mm, the new iPod is considerably thinner, fractionally narrower and massively taller. It's also noticeably lighter, at 3.1 ounces (88 grams) compared to 3.56 ounces (101 grams) for the outgoing model. The crimson hue sets up a nice contrast to the white bezel around the glass on the front, as well as the white plastic that forms the rim of the 3.5mm headphone jack, which still lives on the bottom.
