I'd say this is an intresting concept, given that lots of people are into fair-trade goods. I have to confess I myself buy only fair-trade coffee and tend to also buy other imported foodstuffs as fair-trade if available.

How is the visibility going to be verified, would there be need for an organization certifying fair-trade electronics

On another trend, as I also am into local grown food [I don't really know what's the english term, in finnish it is "lähiruoka" which means supporting your neighbourhood farmers or growing your own groceries (and animals too...)]
Would there be popular demand for "local grown phones" also?
