Now I will ask you, why would someone want to throw away a computer they have replaced? I realize old is old, and new is new. I have a 3 piece computer network. True a network would be hard to do with different operating systems. All three of my machines are xp pretty easy to network together. So why would a person throw a computer out, network with the new one, or just hold it for extra parts, drives, cd roms and such. Anyhow I just don't see an end to a computers life... always good for something...
just a thought
