the Environmental impact of PCs

There have been a number of stories focusing on the environmental effects of discarded computers, mostly as a result of the publishing of a book called Computers and the Environment
by the United Nations University in Tokyo. Wired.com have reported on the book, whose major premise is that recycling of computers in not really viable, as the most feasible solution lies in extending the lifecycle of the computer.

Similarly, the Guardian (UK) and the Sydney Morning Herald have also recently covered this topic.

The Wired article is the most interesting discussion of the book because of comments made by one of the editors, Eric Williams, regarding the possible ramifications of extending the lifespan of the computer for current business practices (including the issuing of software licenses).
