When I previously worked for a University, we would often donate old kit to charity. Schools, I think, often benefit from this sort of thing. Indeed, I do recall many years ago whilst in School seeing a donated Mac of some sort. Certainly, there are many non-profit organisations that benefit from computer donations... but is this about to stop?

Well, it could be that donating old kit to schools and suchlike will become a thing of the past. The debate around the security of computer data continues to be an issue, and there are calls for old kit to be destroyed rather than donated. The donation of old computing kit (a socially, economically and environmentally good thing) may become a casualty of the information age. More here.
