former VP of microsoft comes clean on this polygon story that apparently microsoft entered the console business to primarily stop sony.
"Sony was always very arm's length with Microsoft," Kempin said. "Yeah, they bought Windows for their PCs but when you really take a hard look at that, they were never Microsoft's friend. And Microsoft in a way wanted them to be a friend because they knew they had a lot of things we could have cooperated on because they are, in a way, an entertainment company, you know? I mean, at least a portion of Sony is and they had some really good things going there, but as soon as they came out with a video console, Microsoft just looked at that and said 'well, we have to beat them, so let's do our own.'"
