Good look at the issues with the M1 iPad and iPadOS 14 (and still 15). None of them are in the class I entirely discount when someone complains the iPad doesn't work like the computer they're used to.
Two weeks into owning the M1 iPad Pro, I like it. No regrets in the decsion since my laptop never leaves my desk. I've spent a number of days fully working on the iPad without touching my M1 Macbook Air at all.
