Easy (but more than 3) :
1) all Macbook / Macbook Pro's getting GSM slot /5G modem - you just put card there and it works

and touch screens (just like an ipad with keyboard

)
2) rugged / military strength - small ipad pro with 8"/9" screen and the same cameras as iphone 17 pro max, with 10000 mAh battery - and generally ALL ipdas pro gets the same iphone cameras

3) iphone 18 pro with "dual cell/slot" 6000-7000 Si/Ca mAh battery

, pro max with 8000-9000 mAh
4) return of the Jack connector with quad HIFI DAC like in LG V60

5) return of this local station/brick (AirPort Time Capsule) that looks like a small brick that was a dedicated router / backup brick designed to store your laptop/iphone backups/photos/music/movies etc etc instead of using icloud - and it would be expandable and it would have at least 5 nvme connectors for nvme sdd's to allow raid5/raid6/raid-Z volumes ...
6) I would also add one option to all ipads/iphones : in addition to airplane mode, there is also a "sitting in a trench during war" mode - which means a complete blackout of the device and turning off everything - without refresh signals, etc., so that you can sit in a trench, read a book and be sure that no GSM/Bluetooth guided missile will fall on your head (to be clear - Samsung makes a special version of phones for the military, which not only has such functionalities but also software compatibility with military software/hardware, etc.
7) Another functionality for all iPhones/iPads, there's a special mode—let's call it "Graphene OS"—where, firstly, you can create multiple profiles that you can switch between, each with its own IMEI, etc., secondly, everything is encrypted, and thirdly, there's no tracking whatsoever (generally, if you know what Graphene OS looks like, it has the exact same functionality on the iOS side

).
8) Why on earth there is an "ask app not to track activity in third party apps" option in iOS? It's just a gentle suggestion, not a strict barrier? I would definitely implement a hard privacy mode in iOS—where no app has access to track your activity in other apps at all
9) all ipads pro / iphones pro get 2TB variant, pro max with 16GB memory and 4TB storage option (and all storage would be much cheaper as well)
10) also when you connect iphone/ipad by USB-C to a computer, it shows not only photos subdirectory, but also Music and Movies directories - and you can "load" music to ipad/iphone, just by copying mp3 to a /Music filesystem (just like it is done in Android) and after disconnecting a cable iphone/ipad scans music / movies etc and adds the files automatically to Apple Music/etc without the need to use iTunes or any other stupid software that requires synchronization / additional activities
11) in iphone pro, telephoto (5x-8x) gets super macro capability to make close-up shots of all the bees/butterflies/birds etc etc without any need to get close to the subject
what do you think ?
