Oh, so you aren't saying much then, just equivocating terms throughout the conversation. Please stop.

The way your personal ontology cuts the vast range of human computing endeavors into "task" units does not interest me (nor, I suspect, many people in these threads). What does interest me is my own (and their own to them). As the start of this thread clearly pointed out, the computing field learned many years back the lesson of computer multitasking. It enables a decoupling of the computer's task ontology and the user's task ontology. That is good for users, and they, like me, generally like it (as clearly evidenced by their behavior).
If you haven't been intentionally arguing for the equivalent of "being able to get more than one tool out of the toolbox at once is not helpful", then your equivocation on terms (which implied that as your position) has been noise in the conversation.
