How is the technology in a product expected to change over time? If you're expecting modest or radical changes (with presumably big boosts in efficiency, performance, etc.), why build a long life span product? In a rapidly changing environment, keeping old equipment can be detrimental. Servers can last longer than what they are rated for. Depending on SKU, Intel CPUs are rated for 3, 5, or even 10 years of use, however, servers are refreshed/replaced because of the ongoing performance increases per unit electrical consumption from newer CPU SKUs. In businesses where IT equipment isn't core to the business, old equipment is kept around if IT efficiency isn't really a concern, there's a very high cost of re-engineering, or re-certifying a system. If changes are not reasonably expected, then build products that last a long time. One of my children will inherit my kitchenaid blender.
