Lady Bender uses a older Macbook Pro that works well for her home use so we haven’t even looked at the new ones.
Every one I've owned that I've been able to track is still going strong, some twenty years or more! A couple I'd love to track and know how they're doing, and also so I could put their next after me "owners" in jail, because they were stolen from me, each after giving me more than five years of great performance! You generally have to beat Mac notebooks to death with a Mack truck!
But sometimes even that won't do it as there are verified reports of Macs being run over by Mack trucks and surviving with little damage and still running and even one that fell out of a plane from 1500 feet and survived, a bit bent, screen cracked, but still displayed and worked!
