Amazon Kindle is an ebook reader which uses an electronic paper display, reading Amazon’s proprietary Kindle format (AZW format), and connects by downloading content over Amazon Whispernet, which uses the Sprint EVDO network. The Kindle does not need access to a computer. Whispernet is accessible through Kindle free of charge. The day that the Kindle was released, the Kindle Store had over 88,000 digital titles available for download. The initial sale of the Kindle sold out in 5.5 hours.

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 is 450×550 pixels. It measures 5.3 inches × 7.5 inches × 0.7 inches (134.5 mm × 190 mm × 19 mm) and weighs 10.3 oz (295 g). The Kindle’s internal storage capacity is 256 MB, shipping with 180 MB free. A SD memory card expansion slot is present, officially supporting up to 4GB which implies support for SDHC. 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.

Content

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.

Users can download content through the Kindle Store. The Kindle Store is accessed through Whispernet, over Sprint’s EVDO network, which Amazon provides free of charge. New releases and New York Times bestsellers are offered for approximately $10. Classics like Bleak House sell for around $1.99, with free samples available of the first chapter of each book. Subscriptions to newspapers cost between $5.99 and $14.99 per month, magazines between $1.25 and $3.49 per month, and blogs for $0.99-$1.99 per month. Users can send documents to a conversion service which will send a Kindle-formatted file to the device directly for $0.10 or to a personal e-mail account for free. Users can transfer converted documents from a computer to the Kindle via a USB cable or an SD card for free. Access to Wikipedia is offered at no additional charge.

Digital Text Platform

Concurrently with the Kindle device, Amazon launched the Digital Text Platform, a system for authors to self-publish directly to the Kindle. Currently in open beta, the platform was promoted to established authors by e-mail. Authors can upload documents in several formats for delivery via Whispernet and charge between US$0.99 and $200 per download. The authors receive 35% of revenues based on their list price, regardless of discounts by Amazon.
