I recently picked up a Samsung Galaxy Tab S6 ($500); one of the things that has surprised me the most was how comfortable it is to mark up pdf documents with the pen while reading.
This is one of the things I have struggled with the most when trying to move from reading physical print books to ebooks -- I miss marking up the margins and underlining/circling important parts with a red marker.
I did not expect to use the pen of this tablet at all, but I find it is quite satisfying -- even if it is only a psychological thing being able to mark up the document
