Amazon launches Kindle Fire HDX quad-core tablet range – Tablets – News – HEXUS.net. After Apple I personally think that Amazon is making all the right decisions in the Tablet market. The new additions to the tablet range are impressive. I bough a kindle fire HD for my daughter few months back, and it has become her all in one device, for reading books, playing games and studying online. Taking into account that it is half the price to a similar size Apple device I am happy with my decision.
