In 1987 or thereabouts, apple developed a video in which a college professor comes home and talks to his "tablet" computer to prepare his lecture while he does other things in the house. The computer has a "personal assistant" that can suggest and search the internet and respond to the professor.
That's the vison that apple has and someday they'll put it on the shelf. MS has been chasing the MAC OS since 1984 and they'll keep chasing because apple has the ideas.
