Just let it go. If you dont like the Wii U dont play it. But at the same time I dont want or need to know this and I doubt few others do either. Life is really not that complicated.
But if you really need others to explain to you the benefits then so be it. I can play COD on the TV while someone who is sitting next to me plays COD on the Gamepad without having any split screen degrading my experience. I can control 3 characters in Pikmin with great ease compared to using the Wiimote. In Zombi U I can easily control my inventory and do other interactions such as mini puzzles and unlocking doors on the gamepad that couldnt be done on other consoles without stopping gameplay. Which is important to maintain the atmosphere of the game.
I own all 3 consoles and despite buying The Last of Us and GOW assension have barely touched the 360 or the PS3 because the aforementioned games have been so much more enjoyable. And this is just the beginning as time goes on the GP will be used for more and more innovative things.
Or as I suspect you do, play FPS games all day long. Cause they are always bringing something new to gameing experiences lol
