For the uninitiated, the Fire TV Stick is a little USB-size stick with an HDMI port that plugs into your TV and streams movies, TV shows and music from Amazon Prime, Netflix, Hulu, YouTube, Amazon Prime, Spotify and many, many other sources. Its chief competition is Roku, which Amazon recently passed in active user count. I generally prefer Roku's streamers to Fire TV, however, because of Roku's superior interface.

Starting tomorrow Amazon is also selling the TV-control remote by itself, sans stick, for half price: $15 (£15). It's compatible with most recent Fire TV devices, but not with Amazon Fire TV (first- and second-gen), Fire TV Stick (first-gen), or Amazon Fire TV Edition smart TVs.
