Most people buy things because of their function. However, because of the variety of choice, people have a secondary criteria choice which is attractiveness or style. This is mostly the case why most cell phone accessories like Phone Skins sell at such great numbers. Aside from wear and tear, style is a main motivation for these items.
However, Motorola Cell Phone Accessories, among others, are bought to increase its functionality. Accessories like data cables or Bluetooth allow connectivity to computers. This is necessary for some models that have cameras to download captured pictures to the computer for printing. Also, conversely, cell phones that have MP3/4 play capability can use the computer as a source of music or video files. Protection devices like cell phone cases and full body kits give a cell phone proper protection from handling and other wear and tear. Battery chargers, like the iPod Touch Charger, are a necessity. Without a functioning charger the usable life of a cell phone or other portable device is very limited. Most of these products are easily purchased through the internet.
