Let us never forget that we are holding it wrong.
No, because it's offers one of the most consistent UX. It's far from perfect, but Apple manages to make this happen on both iOS/OSX.
It's all well and good trying to hide the complexity, but not if you can't find the features unless you've already got someone who knows the product talking you through it.
JingOS seems heavily inspired as in a massive lack of any original concept. Even the browser shown in the demo looks so much like safari. The notifications on the corner. The swipe up gestures etc.
Even the design story of icons is heavily inspired.
Honest question, how do you add more features + abilities to an OS without adding more menus in more places?
Of course gaining traction as a closed source Chinese OS would be very difficult and unless we can see some code ourselves and run it locally, its all just speculation.
iPad is a device, not OS.
Even Apple calls it iPadOS: https://www.apple.com/ipados/ipados-14/
Their title seems accurate.
iPad != iPadOS != iOS which was your original modification to the title.
My point is, it’s iPad specific. So iPad/iPadOS is fine here, and not iOS.
