My longest living e-device is Kindle both in 2014. There is no perceived loss of value. So it should be important to weight the user expectations into the equation. But the problem is finding the right TAM to make this doable. Tech is converging and it looks like that we are at the point where we could have a device with long living tech base. But Fairphone with e-ink screen, decent camera and battery would be something I would use for a decade.
