XBOne: Most of my friends have one.
Not a plus for the console. If most of your friends were smoking, that wouldn't be a plus for smoking.
Voice commands for TV and streaming services.
You can very much use voice commands on a PC. No one does it because no one actually likes using voice commands, as they have always been fairly cumbersome and faulty. They have gotten a lot better in recent years, but using your controller or keyboard is generally far easier and faster, so people don't care. It's also been around for many, many years.
Exclusives including
There are some good exclusives, but lets not sit here and act like they don't do this specifically so you spend money on their consoles. It's a ridiculous model that limits gamers, it's not some kind of super exclusive that would only run on console. In fact, when these games are released for PC and ported properly, or they are cross platform releases, the games run better, look better, offer more features, and end up being modded. This isn't a plus, it's a huge negative for the IDEA of console gaming, and the nonsense it brings to the table.
Integration with my cable service.
TV Tuner cards have been a thing for just about as long as PCs have been a thing. I've thought about getting one many times because I've never had a TV in a proper location near my PC. These things offer everything that TV recording devices do, and have done so for years before TV recording devices were common. This new fangled features isn't special, it's one more old outdated tech that has been on PC for years that you didn't care about until it was on the console.
Split screen/couch multiplayer.
The games that have multiplayer have it on the PC too. I use a controller with every game that feels made for one, I've at times had my PC in the living room, and many people have dedicated PCs or laptops for their living rooms. You can play any of those games on your PC the same exact way you can your console. Any of them that are exclusive are once again, not bonuses, just issues with the gaming industry currently, and a result of consoles. Couch gaming isn't even remotely a console thing, this ridiculous idea comes up all of the time. PCs that can run games at resolutions and framerates not even remotely capable on consoles are also starting to come out that fit in your hand, or are at the very least, smaller than consoles. So the idea is just ridiculous in my mind. You're limited here, you didn't gain anything.
Wii U: Extensive
I admit that in my opinion, Nintendo is the company in my mind that is doing the best at creating a non computer console. They are taking things that you wouldn't generally do or have on a PC, and using them. They have created consoles, including hand helds, that create an atmosphere when used, and offer unique playstyles and methods for interaction. The XBone and the PS4 are literally just last gen computer tech, and it's a horrible comparison in my mind to try and make. Although I covered the idea of exclusives already, and I think this even applies to the Wii and Nintendo, there are some forms of play that although doable on a PC, are in my mind perfectly reasonable to have on a separate, extremely low cost console that isn't made to give you the best things, but to offer an experience. Comparing the Wii and the other consoles is a recipe for disaster in my opinion, as it's the difference between the right and wrong way we should be doing this whole "PC and Console" thing.
Amiibo!
Backwards compatibility
With another console that used proprietary media. Not a bonus, an issue with the system. You have backwards compatibility with every PC game ever made on a computer.
The Gamepad
All usable on the PC, and the issues we have with the specific ones we have issue with are not because there is an actual issue, but because it was made in a way that makes it more exclusive to the console. If the developers wanted they could easily release drivers for PC. I would bet my life savings that it was developed on a PC and the drivers either already exist, or did at one point.
and it's touch screen.
Would be perfectly usable on a PC. You can in fact hook up your tablet to your PC and use it as not only another screen, but also as a touch screen, moving things back and forth. If someone wanted to, they could easily create apps that would mimic usage like the Wii. We currently have controllers for certain software. I've used the VLC remote for instance right over my phone. No issues.
The ability to play games on the toilet using the Gamepad's touch screen.
Can be done with any reasonably powerful tablet. Have you really not seen this done before? Something like the Shield is even made specifically to do this kind of thing. There are even entire gaming services for streaming, so that your device doesn't have to do the work. My phone for god sakes was made to stream PS3/4 game to it for me to play. There is little to no difference in using the phone for PC games. My phone even has native controller support because of this little feature, proving that it's perfectly reasonable to have.
Split screen/couch multiplayer.
Nothing to do with console exclusivity, as I already said.
