"Here's a little thought experiment to take into the New Year. Not as difficult as Schrodinger's Cat, but thought provoking nevertheless. Imagine that you woke up tomorrow to a world without Microsoft. Not a world where Microsoft never existed, but one where it hit some hidden critical corporate mass and imploded, or it was discovered that the Windows source code was actually the DNA sequence for red cabbage, and all the directors disappeared to a hidden undersea stronghold. Whatever really... Microsoft existed and now it doesn't."
