Best Amazon Kindle

The Amazon Kindle is an e-book reader developed by Amazon.com subsidiary Lab126 which uses wireless connectivity to enable users to shop for, download, browse, and read e-books, newspapers, magazines, blogs, and other digital media. The Kindle hardware devices use an E Ink electronic paper display that shows up to 16 shades of gray, minimizes power use and simulates reading on paper.

There have been several iterations of hardware devices for this platform, including a main Kindle pdf line (first introduced 2007) and a Kindle DX line with a larger screen (introduced 2009). Devices with touch sensitive screens (Kindle Touch), and a tablet computer with a reader app and a color display (Kindle Fire) were announced in September 2011, along with a keyboardless low priced (Kindle) model. With the introduction of the 2011 Kindles the original Kindles are renamed Kindle Keyboard.

Amazon has also introduced Kindle software for use on various devices and platforms, including Microsoft Windows, iOS, BlackBerry, Mac OS X (10.5 or later, intel processor only), Android, webOS, and Windows Phone 7. Amazon also has a "cloud" reader to allow users to read, and purchase, Kindle books from a web browser.

Content for the Kindle can be purchased online and downloaded wirelessly in some countries, using either standard Wi-Fi or Amazon's 3G  "Whispernet" network. Whispernet is accessible without any monthly fee or wireless subscription,[4] although fees can be incurred for the delivery of periodicals and other content when roaming internationally beyond the customer's home country. Through a service called "Whispersync", customers can synchronize reading progress, bookmarks and other information across Kindle hardware devices and other mobile devices.

In the last three months of 2010, Amazon announced that in the United States, their e-book sales had surpassed sales of paperback books for the first time.
