The Kindle Keyboard was available in two versions. One of these, the Kindle Wi-Fi, was initially priced at $139 and connects to the Internet via Wi-Fi networks. The other version, called the Kindle 3G, was priced at $189 and includes both 3G and Wi-Fi connectivity. The built-in free 3G connectivity uses the same wireless signals that cell phones use, allowing it to download and purchase content from any location with cell service. The Kindle Keyboard is available in two colors: classic white and graphite. Both versions use an E Ink "Pearl" display, which has a higher contrast than prior displays and a faster refresh rate than prior e-ink displays. However, it remains significantly slower than traditional LCDs. An ad-supported version, the "Kindle with Special Offers", was introduced on May 3, 2011, with a price $25 lower than the no-ad version, for $114. On July 13, 2011, Amazon announced that due to a sponsorship with AT&T, the price of the Kindle 3G with ads would be $139, $50 less than the Kindle 3G without ads.
The all-new 2015 version of the Amazon Kindle Paperwhite sends the Kindle Voyage packing. The Voyage already struggled to justify its high $199 price tag beyond the strength of its 1,448-by-1,072-pixel, 300-ppi E Ink Carta screen, and now, the new Paperwhite has the same sharp display, without raising its original base price of $119. This year's Paperwhite also has increased RAM for faster performance, along with access to Amazon's superlative ebook store. The Paperwhite is the best ebook reader you can get for the price, and an easy pick for our Editors' Choice.
