Hi, Mike and all.
I don't think the RP is really to teach young people how to be
programmers, rather, it's to teach them how to be tinkerers. This is
entirely my view, based on nothing at all from the people behind the RP.
Programming can be learned on the PC, but tinkering, that is, putting
hardware and software together, is easier to learn on a device like the RP.

I haven't missed the point of the Raspberry Pi at all.
The guys that have created it have been heard on Radio Four saying the way
ICT is taught in schools does nothing more than teach kids how to be a
secretary and that Microsoft is god. I agree with that sentiment.
But the way to teach a kid how to be a programmer is different now than it
was thirty years ago.
Sure it is good for running a webcam, or as a data-logger, as a radio ham I
could probably find uses for it in my radio shack. But it is never going to
fire-up thousands of kids imaginations when they would be better off with a
PC and one of the thousands of downloadable and free programming tools
around.

I can't help but think that a few people here have massively missed the
point of the Raspberry PI.
It wasn't primarily designed to be "a computer to use as a PC", it was
designed to be a learning tool or something to use when a traditional PC
isn't viable. For example, I don't want to leave 300 watts of base unit PC
running 24 hours a day just to run a webcam, a night-vision camera and
upload data from a weather station every 5 minutes. So a PI can sit there
using about 3 watts doing all of the above.
The fact that it has HDMI HD output and can play blu-ray quality media is a
bonus and has certainly helped enthusiasm beyond the core educational
market.
But what the PI is more about is learning the core principles; if I connect
an LED to that pin and type this command, I can make the LED light up.
If I carefully apply 5 volts to this other pin, I can make a loudspeaker
say "ouch".
You say you "doubt the ability of the Raspberry Pi to fire the imagination
of young prospective developers" but it's already sold around 750,000
units, back-orders are running at 2 million currently shipping late
December and they are making 2,000 a day in Wales and 4,000 a day in China.
There's no reason at all why it shouldn't run vinux - it seems kind of
pointless to have one computer SSH into another computer when the second
computer is technically able to run Vinux, it's just the community
willpower it needs. According to the last message in this list:
https://groups.google.com/forum/?fromgroups=#!msg/vinux-support/i2na-lY8MYs/
6zJTtq7WIeoJ
"Debian for arm does list espeak espeakup and speakup so guessing that is a
good start".
If you want to go simpler still, try something like Arduino or its
Freeduino clone; for as little as £15 you can get an established and
pre-assembed prototyping board with loads of digital and analogue inputs
and outputs. In fact, I'm close to building a light-operated chicken run
door opener and closer for around £25 including solar panel, motor, light
sensor, breadboard, battery etc. As a bonus it will measure and store
exactly how many hours or sunshine there were each day and what time it got
light/dark enough to activate the motor to pull the door.
Incidentally, you don't HAVE to use Python to programme the PI - a friend
of mine has written an internet enabled remote door-unlocking device with a
display, pin-pad,
All these things are what you make of them!
