"Whenever I read a Sony or Microsoft press release or meet with company representatives, they're quick to point out that Nintendo's Wii console isn't a competitor. Why? They claim it's because the Wii does gaming differently and is more of a "casual" platform than a "true" gaming console.
Earlier this year, Microsoft's Aaron Greenberg, director of product management for the Xbox 360, said the Wii isn't a competitor at all.
Sony isn't innocent either, of course. Just a few weeks later, the company's CEO, Howard Stringer, told Bloomberg that he's played the Wii and he's not impressed."
