In the scheme of things, please realize that 5 years is not "extremely long lasting", it is fleeting and the damage to the planet (and people) for those 5 years will take millenia to repair, if it even can.
The timespan is from purchase to date. The devices are all still in working condition. I can't predict how long they will last. You are of course right but I don't think giving up generic computing is the answer though.
