Apple is definitely not the worst in this regard, but the most recent version of iOS to support the iPad 3rd generation (the device we are discussing which is being used as a PDF reader) is iOS 9.3.5 (a security/bugfix release on August 25, 2016 which supports the WiFi-only version of the iPad 3rd generation) or iOS 9.3.6 (also a bugfix release on July 22, 2019 which supports the WiFi+cellular version of the same device - specifically, this was a fix to keep GPS working).
The iPad 3rd generation was released in 2012, so the 2016 9.3.5 iOS release gave 4 years of security/bugfix support for the WiFi-only version of that device.
The homelab and professional editions have lifetime licenses available - I didnt notice them in the pricing section but there’s a link to them in the FAQ
I use an iPhone, and my Messages app is using 72GB at the moment (and it would be a lot more if I hadn’t lost all my history about 5 years ago). The issue is that extended family members send a lot of media (mostly family photos / videos) via group messages, and although there is a way to expire messages older than a certain age, there isn’t a way to only expire media from messages older than a certain date and/or automatically bulk export media from messages (you can do it manually, but we’re talking a LOT of media here). I guess I just haven’t been disciplined enough or had enough time to export media I wanted to keep and then remove it from Messages as time went on.
In any case this feature wouldn’t benefit me, because I don’t think any of my extended family would want to use it.
Flights seemed to be one of the use cases they talked about being an amazing immersive experience even though you’re physically confined to a (usually) small seat. What about it didn’t work?
