It"d be a lot more than an extra £5-10. Small batches are completely uneconomical to make; the 50 alpha boards we made last year cost considerably over a hundred pounds each to manufacture because the batch size was small. Prices per board decrease (pretty magnificently) the more you build.
We don"t believe there are the 10k or thereabouts electronics patriots out there your model would require who will only buy a UK-made Raspi, but if the numbers are any smaller than 10k, you"re talking about machines which will cost far, far too much for us to deal with. Not to mention the added work for the foundation (and remember that in practice, it"s really just Jack, me and Eben working with the factories, and there is a vast amount of paperwork involved); it"s not just a case of shaking somebody"s hand and saying: "Go forth and make me a computer."
The Union Jack emblazoned, UK-only board for angry lunatics^H^H^H^H^H^H^H^Hpatriots is a charming idea, but it"s not remotely realistic.
First of all, thanks for taking the time to provide a reasonably informative post. It took a bit of time, but at least here it is.
Regarding your unfortunate lunatics/patriots comment, you shouldn't let your prejudice get the best of you. I don't believe it is a good idea to go around accusing Raspberry Pi supporters of being lunatics. It simply isn't a good PR strategy to interact with people interested in it with so much scorn.
In addition, I am not from the UK, nor did I ever set foot on it, or ever intended to do so. Patriotism, or any nationalistic feeling, was never a factor in this suggestion. You should had understood that, and it amazes me how you didn't.
Finally, I'll say only this: if you want to curb the amount of arguments in this forum then you could at least try to tone down the propensity to post passive-agressive and provocative comments. It doesn't look well for a charity dedicated to an educational project to have its PR done by someone who is unable to have a polite and educated conversation.
