Available in two sizes - 6 and 7 inches, the Fire HD is also on offer in five colours. Essentially a smaller version of the HDX, Fire HD take advantage of Amazon’s latest mobile operating system like it’s bigger sibling. This means software like Family Library where family members can share content, and ASAP, which predicts the media you’re going to view next. The 6-inch is priced at £79 and the 7-inch at £119, making it very competitive too.
