I've divided up my list of iPad apps for writers into sections for: (1) Writing apps that focus on longer notes and documents, (2) Brainstorming & outlining apps, and (3) Other useful tools for writers.
These days, there are SO many iPad apps in the iTunes store just for taking quick notes that I can't possibly review them all. See the bottom of this page for a list of other people's reviews and lists of iPad apps for writers.
