Wow ... in your business/personal life YOU might not find you have a need for an iPad, but for others of us here they can be very useful and productive. Different people have different needs.
I have a 12.9 inch iPad Pro which I use all the time. My wife has been finding that it is very useful for her also and is always borrowing it and wants one of her own. I’m waiting for the new 12.9 inch models to come out in the next month or so and then I’ll get her one. Then I can have mine back.
"...which I use all the time..."
My spouse was given one for a present and doesn't use it.
I refuse to read books on a machine...I read BOOKS!
I have a laptop.
My iPhone is usually locked/shut off.
I watch T.V. and discs on a T.V.!
There is absolutely NOTHING that I need an iPad for.
I'm not saying that others may find a use for it, though I can't imagine what, should they have a computer, laptop, and iPhone.
