See the thing is, people have to want these features. If one of the features of the X1 was that it randomly released putrid smells into the air while playing, no one would be "where is the PS4's fart feature? Sony has let us down!". The complaints about the Switch lacking this and that is because these are features people want, these are features people expect from a console in 2017. Many of the people complaining about the Switch missing features would gladly trade most if not all of the features you listed as an "advantage" for the features that are important to them.
So, nobody wants 2 controllers out of the box, or a touchscreen controller? I have a XBox One, and to be honest, I find it archaic having to type anything with a controller now. We're not talking about some imaginary concept here. We're talking about having to click an arrow button (or analog stick) to letters of the alphabet in order to string words together in 2017. To me, that is the epitome of ancient technology.
So imagine taking your Xbox One controller, and turning it sideways so you hold the controller in such a way that the thumb stick is on one hand, and your other hand is able to grab the face buttons. That's one thumb stick, and 4 buttons. Now, ignoring how uncomfortable that is, imagine playing a game like Forza, or Halo, or Gears of War with just those buttons. That's the same amount of inputs one Joy con has. Many people look at the joy cons, notice how they individually have substantially less inputs than a standard controller (almost half) and don't really consider them to be real, serious controllers. If I get the Switch I will likely never use the Joy cons individually, because I know it will be a sub-standard experience vs a traditional gamepad. I remember playing FIFA using just a horizontal Wii Remote, and it was terrible. Its seriously limits the amount of control you have over the game compared to a pro controller, and I can't imagine this experience being much better just because there's a thumb stick instead of a d-pad and there's an extra shoulder button. It's just not a great experience for me, and I don't see it being a great experience for many others.
Do people want touch screen controllers? I don't know, perhaps you should ask Wii U owners or Vita owners. I think that pretty much sums it up, but anecdotally, many people can't stand the touchpad on the PS4 controller. I know many people that would glady buy a controller with no touch pad if it meant a lighter controller or longer battery life. It serves little purpose. Speaking of which, have you used a PS4 controller? They have an on-screen keyboard mode that uses the gyroscopes in the controller to navigate the keyboard. It's very intuitive and very quick to type, and is definitely much easier than typing on my PS Vita for example. I actually find typing on my vita to be cumbersome.
Besides, considering the touchscreen isn't even available while docked so it'll likely recieve very little support.
