While the new Kindles are upgraded in several ways, Amazon also cut the price on what will be its entry-level 7-inch tablet, the Kindle Fire HD with 8 gigabytes of memory, to $139 from a $199 version that had 16 GB of memory.
That makes the tablet just $20 more than Amazon's latest dedicated e-reader, the Kindle Paperwhite. The Kindle Fire HD is sheathed in a new magnesium alloy body like the HDX models, but has the same screen resolution and processing power of the older model.
