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.
Several hardware devices support this platform, including a main "Kindle" line and a parallel "Kindle DX" line. The most recent Kindle device is the third incarnation of the main line, officially named "Kindle", but usually referred to as "Kindle 3". Kindle 3 was released on August 27, 2010. User reports indicate that the new display on the Kindle 3, with E Ink Pearl technology, is noticeably superior to that of prior generations.
The Kindle DX line features larger screens than the main Kindle line and is marketed as more suitable for displaying newspaper and textbook content. 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 and Windows Phone 7.
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, 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.
A first generation Kindle
Amazon released the Kindle First Generation on November 19, 2007, for US$399 and was sold out in five and a half hours. The device remained out of stock for five months until late April 2008.
It is the only Kindle with expandable memory, via an SD card slot.
The device features a 6 inch (diagonal) 4-level grayscale display, with 250 MB of internal memory, which can hold approximately 200 non-illustrated titles.
Amazon did not sell the Kindle First Generation outside the United States. Plans for a launch in the UK and other European countries were delayed by problems with signing up suitable wireless network operators.[18]
A second generation Kindle
On February 10, 2009, Amazon announced the Kindle 2.
It became available for purchase on February 23, 2009. The Kindle 2
features a text-to-speech option to read the text aloud, and 2 GB of
internal memory of which 1.4 GB is user-accessible. By Amazon's
estimates the Kindle 2 can hold about 1500 non-illustrated books. Unlike
the Kindle First Generation, Kindle 2 does not have a slot for SD
memory cards. It was slimmer than the original Kindle.
To promote the new Kindle, author Stephen King made UR, his then-new novella, available exclusively through the Kindle Store. On October 22, 2009, Amazon stopped selling the original Kindle 2 in favor of the international version it had introduced earlier in the month.
According to an early review by iFixIt, the Kindle 2 features a Freescale 532 MHz, ARM-11 90 nm processor, 32 MB main memory, 2 GB moviNAND flash storage and a 3.7 V 1530 mAh lithium polymer battery.
On November 24, 2009, Amazon released a firmware update for the Kindle 2 that it said increases battery life by 85% and introduces native PDF support.
On July 8, 2009, Amazon reduced price of the Kindle 2 from the original $359 to $299. On October 7, 2009, Amazon further reduced the price of the Kindle 2 to $259. The Kindle 2 was criticized for its high original retail price, compared to the $185.49 manufacturing cost estimated by iSuppli.
The original Kindle 2 uses CDMA2000, for use on the Sprint network. The international version uses standard GSM and 3G GSM, enabling it to be used on AT&T's U.S. mobile network and internationally in 100 other countries.
Kindle 2 International Version is believed to have a noticeably higher contrast screen, although Amazon does not advertise this. Another review done by Gadget lab, disputes this and actually states that the font appears to be fuzzier than the first generation kindle. The review goes on to say that changes to the Kindle 2 have made it harder to read the smaller font sizes that most books use. On another website they also discuss how the font size is at times worse than the Kindle 1's. It appears that whether or not the Kindle 2 is clearer or fuzzier than the prior model depends on the font size.
On October 22, 2009, Amazon lowered the price on the international version from $279 to $259 and discontinued the U.S.-only model. On June 21, 2010, hours after Barnes & Noble lowered the price of its Nook, Amazon lowered the price of the Kindle 2 to $189.
