My friends who have Android phones seem to upgrade them almost twice as often as I upgrade my iPhone (about every four years). I’m still using my mid-2015 MacBook Pro for work every day, it’s a little long in the tooth so I will upgrade early next year (assuming there is a new Apple Silicon model around the end of this year). That will be six and a half years of heavy use out if it, which is longer than most laptops I’ve had from other brands have lasted…
