Yeah, the Mini is my favorite device to use casually at home. Since I use it so much and like to keep it with me, my only issue is it doesn't fit in my pocket. So if anything I wish it was a little smaller, either that or I wish it folded.
But I also have a 13" iPad with keyboard, which I use almost exclusively as a laptop (I also use the Pencil, otherwise I would have a MacBook Air or Neo). To me the two iPads have very different purposes, but if I had to choose one, I'd have to choose the 13" with keyboard only because productivity is higher priority than entertainment (even if I spend more time in entertainment). I wouldn't get a 11" iPad as a compromise to try to do both for the same reason. I'd rather prioritize productivity and just use my phone and TV for entertainment.
But that's me and my particular situation. Everyone is different.
