just because you don't need portability doesn't mean other people don't. the world doesn't revolve around your needs.Dirty Hipsters said:it isn't designed at all for an adult audience.
The WiiU's touch screen controller is great for when your dad wants to use the TV to watch sports and doesn't let you play video games on it. You can just turn on your WiiU and leave the room with the controller while playing on the second screen!
...Except that I'm an adult, own my own TV in my own living room, and don't have to worry about people kicking me off my TV. I don't need a portable second screen because I have A FUCK OFF BIG TV SCREEN all to myself.
The Switch's portability is great for when you have to go on a long car ride with your parents and have nothing to do. You can just pull out your switch in the back seat and play it on battery power until the drive is over.
...Except I'm an adult and I'M THE ONE DRIVING THE CAR. I'll never actually need the Switch's portability.
there are still millions of people who take public transport and catch airplanes etc. and of course, millions of kids will use it on car rides and or when their parents use the tv as you already pointed out.
but alas, the Switch will fail specifically because you don't need any portability in your life.
