Hi, I've only given this a quick once over. I liked it for the most part -- I think you've collectively brought some important issues to the fore. I would have liked to see some idea of perspective from within developing contexts, but I assume that would be difficult given how you describe yourselves as being from the Bay Area.

On the environmental issues, I think it important to go "full circle" with the toxic chemicals and metals used in the production of cell phones & also address the fact that some of the metals are mined in slave-like conditions in Africa. Like War Diamonds, I believe the profits are also used to fuel wars. The New York Times Magazine did an expose of this issue in 2001. You should dig that up... it is all part of the ecology of the cell phone & one which is particularly hidden.

Also, on recycling technology, I think more could have been said about what happens (or doesn't) to used computers and cell phones now -- exportation to developing countries where they are stripped down for the metals in them. The rest ends up in the garbage -- land fill. Check out the Silicon Valley Toxics Coalition for more on this.

Thanks for making such an important "dent" on these issues! I've also put it up on my blog: http://edublog.kmdi.utoronto.ca/ZeroCostComputing/
