And here I am sitting at my 2011 Dell Latitude wondering what is so special about that. My sis had my 2013 Sony Duo but that's now become unusable with its broken, built-in battery. Yes, 5 to 8 years of service is nice, but not great or out of norm for a $1000+ laptop.
Parent is talking about laptops, I am talking about laptops, why are you talking about smartphones? Though I also had my Samsung S2plus from 2013 to 2019 in use, and that was fairly cheap. I do not know any IPhone users that had theirs for longer.
