Released earlier this year, Amazon Fire has a simple and intuitive interface and a solid voice search for finding movies and titles. It offers content from all the major players, but Amazon content is front and center and voice search works only on Amazon and one or two other content sources. There are some limited parental features as well, something not typically seen in this market but nice to have if you have children.
It's also worth noting that if gaming is a consideration, Amazon says it has that covered by offering a game controller add-on and access to a collection of games designed for larger screens.
