Amazon, no doubt drowned by a deluge of Apple-related news, has released a flood of new Kindles. At the top end, there's a brand new magnesium-body Kindle Voyage e-book reader and an updated Kindle Fire HDX 8.9. At the low end, there's a new 6-inch Kindle Fire HD6 (just $100!) and a new $80 Kindle e-book reader with touch controls. And finally, in the middle, there's the Kindle Fire HD Kids Edition -- a ruggedized kid-proof tablet that comes in 6- and 7-inch flavors, costing $150 and $190 respectively.
