In the seventies and eighties you just didn't see Japanese cars on the road in Michigan. The Big 3 execs all drove each others products but never a Toyota or a Honda.<p>They could see on paper they were losing market share to the Japanese but it didn't seem real to them until it was too late.<p>Reading Scoble's comments about not seeing Windows Phones until landing in Seattle made me think maybe the same market blindness is possibly happening to the Microsoft execs.
