You're not exactly wrong, but you're not 100% right either.

Consoles have one thing that PC's don't, a streamlined experience tailor made for your TV. People do more than just play games on a console, they stream Netflix, interact with their friends through sharing videos and clips, listen to music on their home entertainment system that's already connected to the TV.

Valve has been trying REALLY hard to get to this point, but every time they add something new to the Steam platform it feels half baked in comparison to Microsoft's offering in particular.

Personally, I'm a PC gamer first - the lack of an integrated experience doesn't bother me when I just want to play games. My friends all use Discord for voice/text communication, I can use AMD's software to handle recording video and share it wherever I please, or use OBS to stream to twitch. But, I'm also a professional who uses computers all day and know how to put pieces together to fit my workflow - my friends are at least competent enough to do the same, but my wife or other groups of friends may not be.

Some people just want to buy a box, plug it in and have everything they want. That's the selling point, and unless Valve pulls some huge overhaul out of their butt's that is an advantage that consoles are going to retain.

You'll never get the same performance for the same cost on PC. They showed forza horizon 3 running at 60 FPS/4k on the scorpio, in a stress test with wheather effect + the maximum amount of cars on screen, while only using 66% of the available GPU power. And that was on a version of forza that was not even yet optimized for the scorpio, all they did was spend 2 day updating the engine to run on scorpio. I'm not sure how much the scorpio will cost, but the NVidia 1070 struggle at running forza horizon 3 at 4k at over 50 fps. Getting anything more than a 1070 will likely cost you close to the price of the scorpio just for the GPU.

Specs to specs, PC would seem like a good deal for the price, but with all the optimization that goes into tweaking consoles to make them perform better on games, its rarely the case for a PC to outperform a console for the same price. For example, they announced a hardware implementation of DX12 into scorpio, which isn't available on PC yet. We don't know how much this will affect performance, but its the kind of things that plays in favor of consoles.
