Amazon introduced on Wednesday its third generation Kindle Fire tablets, marked by the letters HDX. The new tablets features 7-inch and 8.9-inch screens and have a mid-October shipment schedule.

The devices will run faster and last longer because of its 2.2GHz Qualcomm Snapdragon 800 quad-core processor that has 3 times the processing power, 2GB of RAN, the new Adreno 300 graphics engine, a new 8MP rear-facing camera on the 8.9-inch model and front-facing HD camera on the 7-inch model and 34 per cent lighter design.

"It's been just two years since we introduced the first Kindle Fire and the team is innovating at an unbelievable speed ... 2.2GHz processor, 338 ppi display, new 34 per cent lighter design, Fire OS 3.0, and new exclusive features like the Mayday button, X-Ray for Music Second Screen, and Prime Instant Video downloads. We've worked hard to pack this much hardware, innovation, and customer obsession into these prices," Maximum PC quoted Amazon.com founder and CEO Jeff Bezos.

Prices of the 7-inch model begin at $229 for the 16GB with Special Offers and goes up to $424 for the 64GB $G LTE without Special Offers at AT&T or Verizon.

For the 8.9-inch model, prices start at $379 for the 16GB with Special Offers and end at $594 for the 64GB 46 LTE without Special Offers at AT&T or Verizon.

Amazon started to accept pre-order for the 7-inch Kindle Fire HDX and 8.9-inch Kindle Fire HDX with shipment dates beginning Oct 18 and Nov 7, respectively. But the LTE models will ship later by Nov 14 and Dec 10, respectively.

The Mayday button Bezos allow users 24/7 access to free tech support by just tapping the button to be connected to a live Amazon export who will offer help in navigating the new device by drawing on the screen. Amazon aims for a 15-second or lesser response time to Mayday requests.

The agent could not see the user, only what's on the tablet display, as a way of protecting user privacy and to prevent ChatRoulette type of shenanigans.

The Kindle Fire was the first affordable colour table offered by a major hardware maker and the first respectable tablet that fits in a coat pocket introduced in the market in 2011.
