Their suggestions include: upgrade instead of replacing, go for LCD monitors instead of CRTs and, if replacing, reuse the old one as an MP3 server on your home network."
But, I used this to my advantage -- when the Linux server recently took up smoking as a new hobby, instead of fixing it, I was able to get approval to spend money on a G4 on the condition that I get rid of both the Linux server and the Smurfy G3. Imagine: buying new hardware will actually make my wife happy!
