say goodbye to FB and the kid running it. Gates will squash GOOG, FB and APPLE just like he crushed AOL, Netscape and Oracle and SUNW. When he comes back, the justice department cuffs won't be on him like they were when he retired. Gloves off, billions in cash and his ruthless style only matched by Jobs will mean MSFT back to #1 and a $TRILLION Market Cap.
You write as though Gates has not continued as chairman of the board, instrumental in defining MSFT's strategic vision and having ultimate control over the business. Ballmer was "running" MSFT only in the sense that Medvedev was running Russia as president, with Putin as prime minister. Gates IS indeed back--because he never left.
his wife won't let him come back as CEO - but I enjoyed your fantasy for a bit. As long as Balmer goes and they replace with a true visionary I will be happy. $100/shr would be quite nice on its way to 200.
