If consoles sales are all about the software, then what's the point Wii U's second screen?

I think it's there just because Nintendo is set on the idea that they can't just make a console anymore. It has to be different from their previous console, and it has to be different from the competition. While this worked for the Wii, the difference is that the Wii had a good gimmick and a killer app that explained that gimmick perfectly to customers. The Wii U seems to be something that Nintendo themselves isn't even really enthusiastic about, the screen having been a differentiator that they don't necessarily believe in but felt obligated to make.

There may be a killer app yet for the Wii U, but Nintendoland was definitely not it, and the fact that the basic idea of a second screen isn't really appreciably different from the DS with which Nintendo is already very familiar by now makes me think there isn't one coming. If there is, it will likely be something built around asymmetrical multiplayer, which is quite different from what's been done on the DS.

@bold: it's necessary [for me] to mention, Nintendo has this strategy because they believe in low prices, in simplified interfaces, and fun tech.
