Just out of curiosity, have you heard of the Remarkable Paper Pro? I just got one and it's decent at the writing experience. Probably even good. But currently it's basically only for writing, you can export PDF or png to an email or their cloud. You can write on imported pdfs as well.
I know; I was fortunate as a student to have a Gateway convertible(yay complicated hinge mechanism) laptop with a 4 year warranty. It was okay with notes (I did really love OneNote but portability of those notes was not good), and right before the end of the warranty period the hinge failed so they replaced it entirely. It was actually more expensive than the rm paper pro and I would relish the opportunity to have it back then. Granted, it was also a full Windows laptop too, which the paper pro is decidedly not.
