How come Wii is so small?

Infendo

Nintendo president Satoru Iwata reportedly asked his team of industrial designers to make the Wii no taller or wider than three stacked DVD cases. The result, as you know, is probably the sleekest video game console ever made.

Have you ever wondered why that is? I suspect, as I’m sure most do, that Iwata felt the smaller design would appeal more to consumers already familiar with sleek and skinny DVD players, not big, boxy, or funky looking video game consoles.

Anyone else have any insight behind the small design?
