I've used Xbox One a lot when my cousin who owned one was living here and I didn't find the Kinect to be really something necessary. It's more like a hey if you have one with your XB1 then use it but now?? If I had to buy a XB1 I wouldn't even buy it. I think though it depends on one's setup. Like I have all my stuff in my bedroom so my PS4, PC, Switch etc is on that one TV. I prefer using my PC since I'm mostly on it.At this point you will just have to buy an xbox one s with kinect to understand.
I basically have a box full of other streaming capable devices sitting in a corner because the xbox one beats all of them. It's a focus that Mattrick and that original team had and it shows.
I could see someone with a living room setup using this if the PC isn't next to the TV. Still though I felt like the XB1 Entertainment>>>>>>>PS4 discussions are slightly disingenuous especially today.
