It’s amazing how some products become so successful that they create entire industries surrounding them. This is very clear for generic products such (just think at the impact the invention of the TV had or that of personal computers) but is often the case also for specific lines of products by individual manufacturers.
A great example is the whole I craze that Apple has created (Imac, Ibook, Ipod and now Iphone). Not only have these I products become huge sellers, they have created entire industries of accessories. Take pdostore.com for example. The site has dozens of iphone accessories as well as hundreds of other accessories for devices such as blackberries, smartphones and other devices. These accessories both enhance the user’s experience (such as the 3-1 car charger\adapter and FM transmitter for Ipods) and are also designed to protect these expensive devices from any damage. A good way to protect any device is getting a matching carrying case as well as special screen protectors to prevent scratches.
