Semigoodlooking , please elaborate on “as the iPhone/Ipad ages the biggest problem is software. If you enjoy apps then at some point your iPad/iPhone will become useless to you.”
Thanks!
At some point Apple stops supporting a device if it becomes too old. That means new versions of iOS will be available for that device. So, if you buy a new iPhone today, it ships with iOS 14. It will be able to get future version updates (iOS 15, iOS 16, etc.) until Apple cuts support. Once this happens, your iPhone will not get the latest iOS versions.
That means no security updates or fixes for bugs. However, it also means developer support for older iOS versions dries up. Many developers will only maintain their apps on the latest versions of a platfrom, so if your iPhone is stuck on an older version it will not receive app updates and frequently the app will simply stop working on your phone.
This used to be a much bigger problem on iOS than it is now. I had a 1st generation iPad that became almost useless in terms of using apps... still fine for browsing though. I mean YouTube, Facebook, Netflix, Gmail, Maps, all became useless and/or unavailable.
However, Apple has made massive strides in device support in recent years. The company now promises to support all devices for 7 years. That means the iPhone you buy today with iOS 14 will continue to get support right up to iOS 21 in seven years time. The oldest iPhone currently getting iOS 14 is the iPhone 6s/6s Plus, which launched back in 2015. It's last iOS update (15) will come next year. After that, if you happen to still have an iPhone 6S, your app situation will become more sketchy.
It is also worth noting that app developers may continue to maintain their app even if Apple is not offering support of an older iOS version. Another note is Apple's seven-year support is excellent service in my opinion and I think 7 years is fair considering most people will change their phone in that time. For comparison, Samsung only supports phones for four years.
I hope that is not too complicated, but that's how it works.
Edit to add I think support for fixing an Apple product is less than seven years, but I am not sure how much. So, if you're device breaks and you wants an official fix, it's worth checking how long Apple provdies services for.
