I'll do you one better - I still have a 2008 MacBook Pro that I use daily, it works fine. Also a 7 years old iPad Mini 2 that still gets security updates. Yes, planned obsolescence indeed.
I have Android tablets from 2014 and an ipad air 2 from 2014. The Android tablets haven't seen any updates since 2016 and are unusably slow while the iPad air 2 still gets the latest updates on day one with the brand new ipads and feels perfectly usable and sees daily use.
