Agree. If you're large enough to have your own pool of replacement
hardware for anything critical, then using it until it fails isn't a
bad strategy. That being said, support for fixing of software security
bugs has probably shortened the production life of a lot of perfectly
useful hardware.

One risk people haven't mentioned is the risk of leaving it in
production so long that people think it is fake ;-)
