Annotation tools on the iPad are useful for grading, taking notes, and reviewing articles. New apps are always being released and can vary in their features and usability. For a brief comparison of popular annotation and note-taking apps, read “Finding the Best iOS App for Annotation and Note-Taking” by Ian MacInnes posted on the Chronicle of Higher Education’s blog ProfHacker.

This list is very comprehensive. I would be curious to hear your thoughts about Notability which stands on a framework of audio recordings linked to notes. This feature combines seamlessly with full-featured handwriting, advance word-processing, PDF annotation, and auto sync to the cloud. Currently, Notability is in several University iPad pilot programs who we interface with on a regular basis.
