I never had the opportunity to use the predecessor of the Sony. Currently I'm using my iPad Pro 12.9" for note-taking (NoteShelf) and reading PDFs. I'm a software developer and mainly read technical PDF documents...
A nice alternative to the iPad is always welcome
1. How solid are the Sony's PDF features (how good have they been with the predecessor?). Cropping margins / remaining that crop on page turn, searching in PDFs, etc.?
2. Is this only for taking notes / annotations within PDF - or can we expect a generic notetaking application?
