A Wii little story
A friend from college visited me a few months ago and we played a few rounds of Wii tennis and he fell in love with the game and wanted one. Then I had to break it to him that it was still currently almost impossible to buy a Wii. He recently told me a story of his coworker tracking one down:
"You gonna buy that Wii you're holding?" says the shoulder tapper.
"Yeah, I think I am."
And he did.
Now that's consumer demand for a successful product.
