Amazon Kindle is an electronic book (e-book) device launched in the United States by Amazon.com in November 2007. It uses an electronic paper display, reads the proprietary Kindle (AZW) format, and downloads content over Amazon Whispernet, which uses the Sprint EVDO network. This means that the Kindle can be used as a stand alone without a computer. Whispernet is accessible through Kindle without any fee. On the release day, the Kindle Store had more than 88,000 digital titles available for download. Amazon's first offering of the Kindle sold out in five and a half hours and the device remained out of stock until late April 2008. It retails for $399 from Amazon.com.
Technical specifications The Kindle features a 6" diagonal, 4-level grayscale electrophoretic display (E Ink material) with a resolution of 600×800 pixels (167 ppi), although the largest graphic image that can be displayed without being resized in a publication is 450x550 pixels. It measures 5.3 inches × 7.5 inches × 0.7 inches (134.5 mm × 190 mm × 19 mm) and weighs 10.3 ounces (295 grams). The Kindle has 256 MB of internal storage, of which 180 MB is available on a new device. An SD memory card expansion slot is present, officially supporting cards up to 4 GB in size. It has 64 MB of RAM. The battery lasts roughly two days with wireless on, and one week with wireless off. The battery charges in about two hours. A USB 2.0 port (mini-B connector) is available for connecting to a computer (where it acts as a USB flash drive). The Kindle features a headphone jack and one-year warranty. The device runs on a modified version of Linux based on the 2.6.10 kernel.
The internal memory of the Amazon Kindle can hold approximately 200 non-illustrated titles. Users can download content from Amazon in the proprietary Kindle format (AZW), or load unprotected Mobipocket (PRC, MOBI) or plain text content. Amazon offers an email-based service that will convert HTML, DOC (Microsoft Word), JPEG, GIF, PNG, and BMP documents to AZW. It also supports audio in the form of MP3s and Audible 2, 3, and 4 audiobooks, which must be transferred to the Kindle over USB or on an SD card.
