"Apple has maintained its attention steadfastly on products while Microsoft has maintained unwavering focus on the distribution and control over value chains. During the 1990s one strategy worked and the other didn’t. During the following decade they changed places. The locus of the two strategies did not change. What seems to have changed is what the market values. So we have to ask: Is the end of the Zune a matter of poor execution or is the cause for failure something more profound? Is Microsoft’s real problem that they have prioritized that which is no longer valued?"
