The reason why Netflix was big on consoles was because it's a visual medium primarily and consoles are usually hooked up to the biggest screen in the house.
With iTunes on the Wii U, there's just no point in it. If you are using iTunes, you already have a device that is more than capable of playing, and likely one of the portable devices that you can use while you play a console.
I wonder if any of these phones even work after all these years.
Again, I see absolutely no point in it on a console. No need to be so condescending if you disagree with me.
You do know that iTunes is more than just music right?
