If you don't update your iPad, if apps stop working it's because the app developer has declared your iPad obsolete probably because older APIs are not supported. It's not something about the iPad or Apple per se. It's hard to understand because software does not degrade with use so everything else being equal it should last an eternity. But in this particular case, everything is not equal because the 3rd party app has moved on.
