My company has been lengthening replacement intervals with every budget cut. In the 1990s it made sense to replace computers as often as every 2 years - the new one would be twice as fast. Around 2000 that slowed down though, and so 3 years made sense. Today computers are expected to last 5 years. If the most common things to break are easy to repair it might make sense for a company to not replace computers are all anymore, just keep the important spare parts on hand. (they still need to keep new ones for weird accidents)
