That might make sense for all those android tablets with 0 years of software updates, but doesn't really work for macs because they get updates for around 7 years (a few years longer if you include security updates). How many 7 year old macbooks are there that's still in use, and of those, how many are getting trashed because the user absolutely needs the the latest updates?
