When I think back to when I was learning to program in 9th grade (I'm
not a professional software devel) I know that it was really exciting to
be able to twiddle with the computer for a bit, then call my mom over
and have her work with my program -- simple guessing games, then
eventually moving on to more sophisitcated things like memory, card
games, etc. At the time I was learning QBasic, so console-oriented input
was what you had.
Granted QBasic had no notion of an interactive console -- or rather it
did, but that was not a predominant way of interacting with it. But even
though it did, it would not have been as exciting to sit my mom down
with it and let her play around, and I wouldn't want to have to explain
to her (even now with a nearly infinitely more sophisticated
understanding of computers and programming than I did in my first
months) what a function is, how to interact with it, what arguments are,
It may not be how you like to teach computer programming or interacting
with computers, but I think there's a very important case to be made for
"other as client" at the very beginning, as a way of keeping it
interesting, when someone else is going to see it.

I don't think programming with, eg, raw_input() is programming for a
newbie, but it is programming *at the level of a newbie* for someone
else who may or may not be -- in my mom's case, sure, if I had made a
GUI that might have been easier for her. but the goal was not to make a
program for her, the goal was to make a program, and having someone else
who could use it was a really powerful motivator that got me to explore
ways to extend it beyond the beginning code that was assigned by my teacher.
