I don't have chubby fingers! ;D
But yeah, I know what you mean. For me, my fingers tend to tap at the wrong keys almost on purpose. Like what I want to say doesn't agree with them. It is the same on a full keyboard, but it is easier to correct.
I have never used an instapot, but I suspect that many would still complain about chopping vegetables, with that becoming a reason to eat something even faster/easier to make.
