On October 7, 2009, Amazon announced an international version of the Kindle 2 with a built-in 3G (HSDPA) and EDGE/GSM wireless modem for connectivity in over 100 countries.
Kindle Reader
Amazon.com's electronic Kindle reader -- a device meant to remove the paper from the page and make reading both more convenient and eco-friendly -- is celebrating its first birthday.
Released in November 2007, the Kindle has sold more than a quarter million units. Its texts account for 10 percent of Amazon's book sales despite the fact that 200,000 titles -- a tiny fraction of the books offered on the site -- are available in digital form.
Ergonomic Design
Kindle books is easy to hold and read. We designed it with long-form reading in mind. When reading for long periods of time, people naturally shift positions and often like to read with one hand. Kindle's page-turning buttons are located on both sides, allowing you to read and turn pages comfortably with one hand from any position.
Kindle books has an easy-to-use 5-way controller, enabling precise on-screen navigation for selecting text to highlight or looking up words.
Long Battery Life—Read for Days Without Recharging
With Kindle's long battery life, you can read on a single charge for up to 1 week with wireless on. Turn wireless off and read for up to 2 weeks. Battery life will vary based on wireless usage, such as shopping the Kindle Store and downloading content. In low-coverage areas or in EDGE/GPRS-only coverage, wireless usage will consume battery power more quickly.
Charge Via USB
Kindle ships with a U.S. power adapter and a micro-USB cable for charging your Kindle from a computer USB port. The U.S. power adapter supports voltages 100V-240V.
Enhanced Reading
Lose Yourself in Your Reading
The most elegant feature of a physical book is that it disappears while you're reading. Immersed in the author's world and ideas, you don't notice a book's glue, the stitching, or ink. Our top design objective was to make Kindle disappear—just like a physical book—so you can get lost in your reading, not the technology.
Paper-Like Screen
Utilizing the latest in electronic-ink display technology, Kindle provides a crisp black-and-white 6" screen with the same appearance and readability of printed paper. Sharp and natural with no glare or backlight, reading on Kindle is nothing like reading from a computer screen. Those who see it for the first time always do a double-take. The screen works using ink, just like books and newspapers, but displays the ink particles electronically. And unlike a laptop or smart phone, Kindle never gets warm so you can comfortably read as long as you like.
