Basically, I'm looking for an iPad app that is capable and fully featured for structured note taking. The purpose is twofold. 1) Take developed, hierarchical notes in lectures, job talks, etc. 2) Outline books that I read but do not own. This lets me have a record of the substantive points of the book that I can then deposit into my Devonthink Library, in order to have something searchable. On OSX, I've been using Circus Ponies' Notebook. It lets me export to various formats, including PDF, I can navigate the levels of the outlining very, very easily, and I can move lines of notes around in case I get something out of order. I know Circus Ponies has an iPad app, but I've heard mixed things. Other apps like Evernote and Pages do have outlining like this available, usually as a bulleted list, but they're really hard to move between indented levels, and to insert or delete or move various lines. Thoughts from fellow iPad users?
