You might want to elaborate on what you’re looking for with the poll. I have a 12.9 pro and a mini 4. I’d vote the pro based on what you want but a new mini this year is the only one I’d update, and would end up becoming my primary iPad. You’ll get bad data based on how this is setup
I bought the iPad Air 4 when it came out. I also have a second generation iPad Pro 12.9. I use the pro more because I love the size. I don’t take it anywhere, I keep it at home.
