I have had the 11” for a few years and always felt to carry around the 8” mini would be good. But I watch films on the train so feel a 13” would be cool. Is it worth having two iPads to do that? And my partner had a mini so is a 13” air a good buy to compliment a Pro? I felt little changes over the 2018 pro I updated to but the £700 more screen Pro or a 13” Air as second iPad may offer something new in 2024 for me. Or should I save money and use my 11” M4 Pro as my travel iPad? The screen sizes are important as I watch movies on trains.
