Apperantly at the 2005 Digital Interactive Entertainment Conference Nolan Bushnell Creator of Pong said he LOVED the Nintendo Revolution Controller.
"The 3D Controller from Nintendo is a very good idea. If one looks at today's controllers with their triangles, crosses, squares and circles, that is uncanny. That is like a keyboard. Humans are interface Phobish."
(Rough translation, but basically what he said).
