This is not taking into account that most people won’t know how to fix the problems that arise from connectors wiggling loose or the replaceable hard drive failing. Additionally, there’s also the problem of the connectors themselves wearing out and breaking: e.g. I have a Lenovo X220 that no longer charges because the power cord connector is broken.
