you are forgetting the composed video output. A scart adapter like the one used for old PS and you are done with 99% of TV around the world.
is it teaching Unix or microcontrollers?
i don't get your complain. obviously it is not the same resolution you'll use on a PC, but still usable.BTW due to mass production, i think cathodic TV are now more expansive than LCD one.
you can program hello world with 40, no?
I've never understood why an old (free) PC wasn't a better choice, either.
Still, is it teaching Unix or microcontrollers?
If Unix, you can probably get some cheap second-hand PCs which people throw out when they upgrade to Windows 8 or whatever.
If what I have seen locally is anything to go by, the Education Department will mandate that every school uses Windows, so the question might be a bit academic.
The whole Pi / price argument reminds me of stone soup.
Yes, it's a nice cheap platform, until you add an HDMI-capable monitor, a keyboard, buy an SD card, download the software and copy it to the card (for which you need a PC/Mac), find a power supply that is not underpowered, and a micro-USB cable without too much internal resistance.
There are getting very jumpy over at the Pi forum, I just had a thread closed down, I was answering questions on the current capabilities of the GPIO pins.Stock question and answer over here but it is a bit of a taboo subject over there apparently:-http://www.raspberrypi.org/phpBB3/viewtopic.php?f=44&t=8668
