Sony Ericsson is currently passing on Windows Phone 7 because it doesn't give enough control, the company's French CEO Pierre Perron said today. In a talk with Les Echos, he acknowledged that his company was talking with Microsoft about Windows Phone 7 but that it liked the customization of Android more. Google's OS allowed for "more product differentiation" in software where Microsoft's insistence on a consistent interface for WP7 would force Sony Ericsson to compete mostly on phone quality and price.
