Decent comparison of the two devices.
My choice is iPad as my primary device. When I hit tasks that I can't do well on my iPad (like inspecting web pages for development) then I open up my Mac...reluctantly.
I've wondered about screensize being an issue though. I'm looking at an M1 MacBook Air to try and figure out if a 13" screen is the issue with the iPad or is it the software?
Currently when I use my Mac Mini it's hooked up to a 27" 4k screen. Yes I can use my iPad with it, but the iPad doesn't support 2nd screen usage well so it's not a fair comparison.
I also plan to purchase whatever new iPad Pro comes out this year.
