@dcole001: This is the best reply that I've seen, and totally agree with it. I would just add that the Xbox One S is also good if you are a casual gamer just looking for an inexpensive 4K video solution, since it allows 4K streaming and 4K Blu-Ray. Although the Xbox One S does not do 4K gaming, it does allow for HDR gaming, so games will still look better than the Original Xbox One if the game supports HDR.
This is one of the best Games with Gold months that I've seen in a long while. Kudos to Microsoft and the Xbox team! I'm especially happy about Streets of Rage and Vanquish.
@Angelraid: This was definitely a typo, as both the Xbox One S and Xbox One X both require an adapter to use a Kinect. They do not have a dedicated port for it.
I hate the UI for the Xbox One. It is too cluttered, and too easy for me to accidentally go into the wrong section. The UI for the Xbox 360 was much better.
