I'm the very first person to call Nintendo out on their poor dicision making when it comes to their hardware, but I do feel Nintendo has a particular advantage with parents that you might have overlooked.
Andrea made a great point regarding the importance of auxiliary features (ie Blu Ray player, Kinect, etc) when it comes to selling a console to parents.
However, I think the demographic of "parents" is changing drastically right now. In previous hardware generations, the average parent was not a gamer themselves. But we're now getting to the point where many parents grew up playing Nintendo games.
I don't have kids yet, but when I do have children my first choice of hardware for them would be a Nintendo platform, because I have such fond memories of playing Nintendo games as a child. The idea of sitting down and playing Mario, Zelda, or Pikmin with my kids is enough to sell me on a console right there.
Still, for right now, I personally come down on the same side as Jeff Mattas: Nintendo simply isn't making a console for me, and that's fine.
