Trying to discredit the person talking to you is a very commonly used tactic, but it doesn't work because my "credentials" are irrelevant to the matter at hand.
And the matter at hand here is: according to your reasoning, you are telling us that it's somehow completely impossible bake this feature into the 2018 due to a hardware limitation, or due to a software limitation Apple CANNOT EVER get around.
Therefore, either Apple is incompetent to give users hardware that can do multitasking, making it UNDERPOWERED in comparison to other Pro options, or there is an inherent software limitation that cannot ever be overcome. They can't ever give you a scaled down version of multitasking because multitasking can't ever be scaled down.
Which is which? Why don't you tell us more about a detailed account on inherent limitations of the iPad, and why it's much inferior hardware compared to the competition that it can't ever do full multitasking?
Or are you just guessing Apple's reasons?
I'm not discrediting your knowledge of multitasking, you did that yourself.
I don't have to guess about Apple's reasons, because Apple already stated their reasons.
But here you are saying Apple is wrong about something you demonstrated that you know little about.
