This chart from Morgan Stanley illustrates how Apple has invaded
people's lives.  There was time when Microsoft had 95% of the
computing market, and Apple was fighting for its life. (That
time is quickly turning into old history, but for some of us it
feels like yesterday.)  At that point, only a sliver of people
had Apple products in their lives. Households were pretty much
either Apple houses or Microsoft houses.   Today, everything's
different. You can own a Windows-based PC and an iPhone or iPad.
This chart shows that 70% of people with Windows products have
an Apple product in their homes.   Apple couldn't win the PC
game, so it changed the game, introducing the iPod, then the
iPhone, and then the iPad.   Today, Apple is the world's most
valuable company, and Microsoft is trying to catch up in
personal computing.
