As a law student, I have to go through tons of PDFs on a daily basis, and with most PDF readers providing limited annotation features or being too expensive for personal use, the note-taking process wasn't efficient at all. The one feature that attracted me to Desklamp was the note-taking and navigation feature - it makes making summaries of documents easier without even moving your attention from the reading, all annotations are available at one place, and you can easily navigate back and forth from your notebooks to the text, making revisiting the concepts much easier. As I used the product more, it revealed many more interesting features which have also helped. Finally, the developers have been immensely helpful, always helping resolve issues and taking into account the suggestions users make to bring out newer and more helpful features.
