Back in the mists of time you used an EPROM (eraseable programmable read only memory) programmer to burn information into chips. When you found that your latest and greatest code had bugs in it you needed to expose the EPROM to ultra-violet light in a natty little UV eraser box to erase the data on the part and then you started again burning it.
(We used to drink coffee slower back then).
Next some bright spark invented EEPROMs (with the E standing for electrically) so you could ask the chip to erase your dodgy old code before asking it to burn your new dodgy code into itself.
Around this time a lot of these chips were still removable so when you inadvertently erased the part you could always go get another one and replace it with only some minor pin bending.
Some even brighter sparks decided that it'd be fun to make the EEPROM parts surface mount so now when a virus kills your code, or you inadvertently kill it yourself trying to update the splashscreen with pics of { Paris Hilton, Ray Beckerman, Bruce Schneier, Chuck Norris }, you now have to whip out your soldering iron and take a deep breath.
In the same way that a lot of flash storage has a little 'lock' switch there were link settings on some motherboards which you could set to make sure the chip wouldn't modify itself or erase itself (although the chips didn't always properly support this).
Similarly various microcontroller parts have a fuse bit you can blow to disable any future updates. There were also all sorts of weird and wonderful schemes such as having a couple of copies of the BIOS so the spare could replace the 'broken' copy.
It seems a shame this hasn't become industry standard (or if it has its passed me by in my state of decrepulousness and please accept my apologies...)
You might want to read some Noam Chomsky. He talks about this type of thing a lot. The important thing to
understand is that as the TV audience you are the product. Your eyes are there to be sold to the advertisers
who pay for the channel. The channel will deliver whatever gets eyes-on to be sold. To expect truth
or quality in mass-media in today's climate is a stretch....
Around £140 for two nodes if memory serves.
I'm not sure I'm that impressed with the state of the stack at the moment, but it serves if you want to have a play.

Not to mention that the money you borrowed was created out of thin air...

Linux and TRON don't really play in the same space. You can embed Linux only so far...
It'd be much more interesting if they'd brought in a comparison with eCos which is the natural alternative to TRON at a deeply embedded level.

Interestingly enough eCos has a TRON API implementation too.
