This has to be taken in the context of electronics’ lifetimes.
A smartwatch that was supported for 8 years is pretty great. Who’s doing better?
But if competitors do better, that raises the bar for Apple and is a net benefit for customers. So yeah, Samsung, Google — here’s your opportunity to outshine Apple.
(Google’s already making noises about supporting newer Pixel phones for 8 years, and have committed to supporting some Chromebooks for 10 years. This is a good thing and I’d like to see more manufacturers get interested in offering longer periods of support.)
For now, I suspect Apple will say they’ll be recycle your watch so the materials are not “wasted”.
