Apple has made it a complex dance that isn’t as clear cut as it used to be. You’ll have to decide what matters to you in newer iPad OS versions to decide if it is worthy of upgrading. The current crop of Pros are so powerful that I think they’ll last as long as the OS is supported by third party apps and your use case irrespective of what Apple does.
My point about a complex dance… Apple used to release iOS updates that contained the same features for all supported devices. It could mean that some features were slower on older devices who lacked the processing power to keep up (or Apple didn’t invest the effort to optimize for them who knows). That’s shifted now and Apple will often support devices for a longer period of time, but the trade off us they now will cut features from older devices on newer OS releases. So you will definitely get iOS 18, but you may not be able to use many of the new features of iOS 18. Similar to the flack around Stage Manager when it launched.
If the new feature is worth it you might still be tempted to move up.
I don’t foresee anything in the iPad space that would fit that bill for me, but your usage will differ and so will your mileage.
Agreed, and this is the advantage of not caring about (and not installing) updates at all: I judge releases on two things: hardware merits and my own hardware’s suitability.
The latter only degrades if compatibility isn’t good enough (which takes years on end for me, especially on iPads), and the former now takes a lot longer.
I wanted to upgrade from my 9.7-inch iPad Pro to my Air 5 for these two reasons: the full-screen design of newer iPads, and the effect of apple forcing my 9.7-inch iPad Pro out of iOS 9 and into iOS 12, which significantly affected battery life.
Now? Now my Air 5 runs a perfect iOS version (iPadOS 15), and the full-screen design makes newer releases less appealing, so I should be fine.
Updates obliterate devices, so users who do update may find their devices unsuitable for use on grounds of insufficient hardware due to iOS updates’ obliteration... and I’ll never experience that.
