Amazon is refreshing its range of Fire mobile devices by introducing four updated tablets to the collection, alongside its Fire TV announcement. The Fire HD 8 and Fire HD 10 joins the existing Fire HD6 in the range, and while the Fire Kids Edition gets some minor changes, the original Fire tablet has been given significantly more attention, with the online retailer redoubling its efforts to make it an ideal entry-level device by pricing it at $50, with an extra bonus for buying multiple devices.
