Besides the updated Kindle Fire HD, Amazon also introduced the all new Kindle Fire HDX family. These systems feature a quad-core Snapdragon 800 2.2GHz processor and are available in a 7-inch form factor with 1920 x 1200 pixel screen or a 8.9" version with 2560 x 1600 pixels.
Both models have a battery life of up to 11 hours in "mixed use" and up to 17 hours when just reading eBooks. The operating system on these new tablets is FireOS 3.0 "Mojito", which is based on Android 4.2.
The 7" model starts at $229 for the 16GB edition while the 8.9" version sets you back at least $379 for the 16GB model.
These are powerhouse tablets. We added the latest graphics engine, doubled the memory, and tripled the processing power with the most advanced 2.2 GHz quad-core processor. Our HDX displays bring together exceptional pixel density (up to 339 ppi), perfect 100% sRGB color accuracy, improved brightness, and dynamic image contrast. You also get up to 11 hours of battery life—17 hours when you're reading.
Even the largest new Kindle Fire—the 8.9"—is startlingly light. We re-imagined our design from scratch, with a new magnesium unibody and molded glass-nylon alloy. At just 13.2 ounces, it's 34% lighter than the previous generation.
Kindle Fire HDX is packed with hundreds of updates, including new email, calendar, and productivity apps, X-Ray for Music, Second Screen, and—in addition to streaming—you can now download Prime Instant Videos and watch them offline.
The 'Mayday' Button
Kindle Fire HDX also introduces the revolutionary new "Mayday" button. With a single tap, an Amazon expert will appear on your Fire HDX and can co-pilot you through any feature by drawing on your screen, walking you through how to do something yourself, or doing it for you—whatever works best. Mayday is available 24x7, 365 days a year, and it's free.
