Amazon didn’t invent the eBook reader, but it certainly has helped make them popular with its line of Kindle devices, commonly called “eReaders.” The original Kindle uses electronic ink technology. The e-ink mimics the printed word and results in less eye fatigue compared to reading on a backlit device. The current Kindle line includes the Kindle Fire, which is a touchscreen tablet computer. Books, magazines and newspapers can be read on the Fire in full color, as the screen of this model is backlit. To get full use of the device, users will need to be in a Wi-Fi network to connect to the Internet. Other members of the Kindle family feature either Wi-Fi-only or connectivity via the Amazon Whisper Net, which connects wirelessly to the Internet via a 3G connection. Customers can download books, magazines, newspapers, music and video content from the Amazon store. Kindles can store thousands of items of content, putting your library in your briefcase or backpack.
