People bought a 499$ Xbox One thinking that Kinect would be a central piece of their next-generation experience, be it games or entertainment. In other words, they bought into MS's PR talk. Now Microsoft is dropping support for the Kinect by not making it a mandatory part of Xbox One.
That effectively means that people who adopted an Xbox One during the first six months have wasted 100$ and are sitting with a useless piece of kit on top of their box. Not only that, but if they chose to buy an Xbox One because of its "revolutionary" entertainment capability, they are quickly realising that the Xbox One has absolutely failed to deliver in that department as well.
In conclusion, future adopters are happy to save a 100$ and get to play Halo while the ones that supported Xbox One's during its first six months got screwed.
