Love them or hate them, MS turns 40 today. They were and continue to be a driving force in the computer industry. Without them, there would be no MS Dos, Windows, Office, and a myriad of other products. They created Excel for Apple, which helped put the Macintosh on the map. They invested 150 million dollars in Apple in 1997. By some accounts this gave apple the capital needed to keep going and reorganize into the juggernaut they are now. Of course they used their market dominance to crush competition in an illegal manner and things aren't all rosy with them right now but they are turning 40 and produce so much for the computer world.
