It's only been two weeks since the Kindle Fire HDX has been on the market, and it's already threatened to take over Apple iPad's dominance in the market -- in fact, it's almost outselling the iPad Air! So, what's the benefit of the new Kindle Fire that is taking the market by storm? 

The Kindle Fire HDX is the third generation of Amazon's Kindle Fire line of tablet computers. It was announced on Sept. 25, 2013 and is available in two models, 7-inch and 8.9-inch. Both versions were available to pre-order in the United States on Sept. 25, 2013. A 7-inch WiFi model was released on Oct. 18, while an 8.9-inch WiFi model was released on Nov. 7, 2013. 

Both the 7-inch and 8.9-inch models contain a Qualcomm Snapdragon 800 processor that has an Adreno 330 graphics processing unit. The models also have a 1.2 megapixel front camera that shoots 720p HD video. The 8.9-inch model has an 8 megapixel rear camera that shoots HD 1080p video. The exterior surface has angular, raised plastic edges with the power and volume buttons located on the backside. The Fire HDX features Dolby Digital Plus audio engine powering the two attached speakers. A normal user will get about 12 hours of battery life from a full charge. 

Both models use Fire OS 3 which is a proprietary fork of Android 4.2.2. It features "Mayday", a button for free tech support available any time, "Silk," a cloud-accelerated browser, the Amazon Appstore for games and apps and Amazon.com services for media content purchases. The tablets can send video content to a supported TV, game console or through a device like a Wireless Display HDMI adapter wirelessly using "Second Screen," but cannot send content via an HDMI cable like its predecessor, the Kindle Fire HD. 

The Fire HDX's UI has a "Carousel" which contains the most recent apps used and ones that have been updated or purchased recently. The Carousel also holds documents, videos, music, and books. The Fire HDX also has a favorites tab in which the user can access the users apps from any other application.
