There are two things everyone should look for in a good set top box: ease of use and versatility. A set top box is terrible if the menus are a horror to navigate and you can't just plunk down after dinner and watch a movie. But it's also terrible if it can't actually play the media you want it to play when you want it to play it. Thanks to Kodi's arrival on the Xbox One this morning, the Xbox One X and Xbox One S are now the most versatile set-top boxes available.
