Devices such as the iPad are more than just shiny tablets. You can actually use them to get things done. They can be very helpful for authors. Take the StorySkeleton for instance. This is a cool application for mapping and organizing stories. Users can export their work in Final Draft 8 and Scrivener 2.x friendly formats. The app is Dropbox friendly.
StorySkeleton is fully interactive and makes it easier for authors to plan out their writing projects. This is a universal application. Not the cheapest one around but quite useful.[where to get it]
