Is that not how generational shifts work?
First you try to force the new tool to fit the old workflow, and then the new tool creates a new workflow. Both parts are painful and full of denial, but the new model is ultimately much better than the old.
I teach with my iPad in the classroom. Pray tell me what good mouse and keyboard support is when I am walking around the room with iPad in hand? And I prefer the simplicity and fluidity of iOS compared to a more bloated and cumbersome desktop OS. I was writing on PDFs in notability using my finger long before the Apple Pencil came out, but there's no denying the pencil has made a very significant improvement in the whole writing experience.
So yes, I agree with the user that the onus is ultimately on the user to make the device pro. That you find it paradoxical says more about you than it does about the people who are using their iPad meaningfully in their everyday lives.
Yes. I fully agree that if the iPad gets too laptop-like then it will cease to be a great TABLET and that's what us iPad users want. If I wanted a laptop or laptop functionality then guess what? I'd buy a laptop. I don't like the idea of blurring the lines between laptop and tablet. Let them both be the best devices they can be without compromise or trying to be something they are not. Both device types have a place in the tech world.
Mouse and keyboard for an iPad? Nah, no thanks. As for what makes an iPad a pro model? Good question. Do you have to have a special license to buy and own the pro models?
