Environmental damage through a proliferation of laptops seems to me to be probably indisputable, but what’s the alternative? Is it fair for rich countries to consume vast amounts of resources but stop poor countries having access to the same services ‘for the good of the world’? Can we really in good conscience deny other people what we take for granted? Perhaps if we were sending out hundreds of millions of Macs or PCs there might be an argument here, but the XOs are massively less damaging to the world than any of those devices.
