The Fire HD 10 was always the odd one out in the Amazon Fire tablet line up. Neither premium enough to warrant its £170/$230 price tag, nor cheap enough to excuse cost-cutting concessions like a 1280×800 pixel resolution screen (resulting in a paltry 149 PPI when stretched over 10-inches), there was little reason to recommend the HD 10 over its cheaper and smaller cousins.

I would, however, recommend the new Fire HD 10. Amazon has fixed the tablet's most glaring issues—the most important of which is the introduction of a full HD 1080p IPS display—while reducing the price to an impressive £150/$150. It even features a hands-free integration of Alexa, instead of the touch-to-talk of other Fire devices.
