KeepNote by Matthew D. Rasmussen is a note taking application that works on Windows, Linux, and MacOS X (and now Pandora). With KeepNote, you can store your class notes, TODO lists, research notes, journal entries, paper outlines, etc in a simple notebook hierarchy with rich-text formatting, images, and more. Using full-text search, you can retrieve any note for later reference.
