I don't look at it like the only advantage of adding Windows 10 support to the XB1 makes it more of a media center.

It already accomplishes that. What you gain is 10's of thousands of games designed for PC's and tablets that work without being rewritten for the XB1. The other benefit is to developers is that they can just add controller support to a game or app to make it compatible to the XB1. The rest of the

How could more games not help?

I can care less what my console does outside of playing games. Everything else i have can do the rest.

People who would want Windows 10 and their universal entertainment system would use their computers, laptops, and others and NOT the Xb1. The Xbox brand has always been tied to gaming and that will not change. Gamers are the ones interested in buying consoles and games are also one of the main reasons they buy one. Why would they care of this Windows 10 integration if they already have a separate computer than can do more?

Exactly,  Windows 10 allows ALL of the games for PC's,tablets, and the lowely smartphones to be compaitble with the XB1 with only adding controller support. 

If you own an XB1, this will add 10's of thousands of games to play on it.  What else could you want from it?

If I own an Xb1 and own a computer, I would personally use the computer more to take advantage of even more features and more space. I would only use the Xb1 for games unique to it. Same with the Ps4. If I am already using my computer for entertainment purposes and more then why would I want to switch to my Xb1 if it has less content?  I wouldn't, I would just continue using the computer and even buy the games there since they're also available in it anyway, and I even have more space to store more games in it's definitive state, while multitasking. 

I would only switch back to the Xb1 to experience exclusive features on it and this Windows 10 integration and the content it offers aren't unique to the console.

like phones are more powerfull than last gen consols right now?

thats still bs. theire not. and smartwatches wont be more powerfull than current gen consoles in 10 years from now

not if we still use silicon chips.

Well I am not even going to sit here and lie like most people are doing. I got a very good pc but if my Xbox One gets some pc functions that work then hell yea I am going to use them if I am already chilling in the living room doing some gaming or doing something else on my Xbox One.

I am not talking about GRAPHICS or GAMES but the GENERAL USE side of it. The CPUs in smartphones are cathing up with the XB1 already and in 7 years, they will be much faster, which means they will be much better at most integrated PC-like features of XB1. So the integrated features are not a compelling reason at all. What else is this generation to do, to get you believe that? Nobody cared about Kinect, or snap functionality, or voice recognition, or the fact that it runs 3 OSes in a VM environment etc etc... Win10 will not matter either since everyone already has a PC. Clear now?
