I'm somewhat disappointed to read this. That still won't stop me from getting a Wii. As one commenter notes, "Playing the Wii is clearly not a substitute for real exercise. However, it's definitely better exercise than 'normal' gaming." The study was paid for by Nintendo, which definitely increases the company's cred with me. As TechDirt notes, 'Perhaps we've just become so cynical about corporate "studies" like this in the past, that it's relatively shocking to find one paid for by a company that shows the opposite of what the company probably hoped to see -- and then to still see that study actually published somewhere."
