Avinash, you are entitled to your opinion just as I am. I really don't see Wii Fit being that big hit that you think it will be. American's are way too lazy. (I should know, I am one!)

Oprah giving out Pontiac G6's (or whatever those craptastic GM cars were) didn't spike sales for Pontiac. Just because Oprah brings it up doesn't mean that it's going to sell 100 billion units and be the coolest thing since Jenna Jameson turning 18.
My pokemon brings all the nerds to the yard. And they're like, "You wanna trade cards?" Damn right, I wanna trade cards. I'll trade this, but not my charizard.
