Amazon introduces new Kindle HD tablets, e-reader

Online retail giant Amazon introduced a new suite of its Kindle devices, from 8.9-inch Kindle Fire HD tablet computer to e-reader Kindle Paperwhite with front-lit display. Amazon unveiled larger Kindle Fire tablets, challenging Apple Inc's dominant iPad with lower prices and a trove of digital content that Amazon hopes will win it a bigger share of the booming tablet market. The debut of Kindle Fire HD is seen as Amazon's new strategy to step up competition against Apple, which is expected to introduce a smaller iPad, possibly called 'iPad Mini'.
