Well, the "power user" will tell you to buy a ferrari if you want to race
other ferrari's.  The old '57 chevy just won't cut it.  However, if you want
to point at all the other '57 chevy cars and say "I can blow 'em out of
the water", fine.  Just don't expect the other '57 chevy owners to agree
that it's necessary.

This quote is for the "power user".  I'm absolutely certain that Peterson
and Silberschatz weren't considering mocrocomputers when they wrote that
book.  Of course, if we followed the computer science model for home
computers, we'd all be programming in ADA or Modula-2, and have degrees
in math to boot. :-)

Heh.  Gotcha.  When I make dinner (let's say Coq a Vin, wild rice with herbs,
a nice tossed salad, and chocalate torte...) I do the following:
	1. get out the recipe for each thing
	2. prepare the Coq a Vin
	3. then prepare the wild rice with herbs
	4. then prepare the chocalate torte
	5. then prepare the tossed salad.

I do NOT cook "everything at once", I prepare things in order and let them
cook "off-line" (no CPU processing necessary, it's all I/O) :-)

I do NOT eat "everything at once", a nicely prepared Coq a Vin requires time
to savor the flavor, and I certainly wouldn't stuff a little bit of everything
in at once.

That is pretty much linear.  You are mistaking autonomos actions for "at the
same time" actions.  You may THINK you can watch TV and read your homework
simulataneaously (multi-tasking), but your still going to fail tomorrow's
exam if if you try it.

The human brain focuses on one thing at a time (conscious mind ... the
nervous system automatically deals with lots of other stuff)

>	The classic about walking and chewing gum, is a perfect example.... :-)

Walking and chewing gum are I/O intensive, and require absolutely no CPU
cycles. :-)  It's analagous (mildly) to reading text on your screen while
Music Construction Set plays Bach (possible on both the Amiga and the Atari ST)

Your AMIGA is at home, and you get MOST of your work done on it.  I.E. you're
a power user.  For you, multi-tasking is "wonderful".  I write a lot at home,
and multi-tasking is an unecessary fribjob to accomplish that particular task.

I leave my REAL work (which requires things like UNIX and VMS and TELNET and
all of those neat things) at work.
