Well I moved from the 12.9 M1 ipad to the M4 13 and wow I think it is a massive upgrade. The screen is absolutely delicious — watching video on it is insanely immersive. Everthing pops on this screen. Think vibrance, contrast, dynamic range. It is truly a remarkable screen and it is a quantum leap from the M1 IMHO. The magic keyboard is also a whole nuther beast now — better key travel, better overall design. And everything is just way faster in general. Blazing, really. I am delighted with mine. But all that said, at the end of the day it is still an iPad and does the same things as older versions. That’s what makes it a tough call.
