Yes - the majority of people view computers as appliances.  They don't want a computer, they want an email machine and a word processing machine and a "show me this website" machine and a music-playing machine.  They don't need 2560x1600@120fps, and they don't care about having 16 processors.  They want to sit down, bang out an email, and do something else, or sit down, type their paper, and be done.<p>Apple actually had something like this in the mid-90s called "At Ease", designed as a child-safe file manager.  You had programs on one tab and files on the other.  I remember it from elementary school, and always felt that a more modern version of that would help less computer literate people.
