Representational: The  image displays a clear visualization of an iPod nano  back and front. It displays the screen, the controls, the hard drive size, black color and the Apple logo for authentication. Importantly only the iPod is shown and nothing else to distract from it.

Abstract: Only the back and front of the iPod is displayed in this image with nothing else in the background allowing viewers to focus on the product. This image would be of use in a catalog since viewers can see the iPod's design like the screen, controls, the shape and physical size. The iPod has a fairly simply but easy to access design so that anyone can use it. A screen for displaying things like menus and song titles, a control for selection/pausing/playing etc. and naturally it is designed for handheld use for travel. The Apple logo also functions as a way for Apple to trademark the iPod.  The iPod control has clear representation of a menu function written while including several symbols denoting different functions.
Symbolic: The iPod symbolizes a product of Apple and obviously the logo is Apples brand or seal. Users and viewers will know this product was created by Apple (or at least trademarked). The Apple logo can also be seen as a seal for a competent product making viewers think, "Oh, Apple makes iPods and therefore the iPod must be a pretty good device". Apple has a long history as a popular computer company and consumers might naturally think of all their products as highly competent so the logo give partial incentive to purchase the iPod. The abstracts of the iPod is an example of Apple's modern functional designs. The product itself is a good representation of the high quality products Apple outputs into the electronic market.
