Consider what consumer technology might look like if products were designed with this sort of time horizon in the first place. I'd expect hardware to be more generally upgradeable/repairable extending its service life and at the very least I would not expect to see products assembled by drowning them in glue. It feels to me like the generational difference in hardware products has been flattening out so 15 years may not be an outrageous practical service life, really.
