I'm an academic looking for a software to manage my PDF files with the following capabilities:
- Organize into folders by topic, read/unread, etc.
- Mac/iPad/iPhone platform
- Can be used for citation management
So far I see two contenders: Mendeley and Papers - however Mendeley doesn't allow for (2) and (4) and although Papers does everything, I have to buy separate licenses for each device which is expensive and annoying.
Am I missing some other option?
