I wrote about Noteshelf back in October, and if there has been a reason to wait before trying this app, those reasons must be gone. Noteshelf is a note-taking app that lets you use a stylus (or your finger in a pinch) to take written notes. You organize your notes into notebooks, and the notebooks are organized on a shelf-like browser. Notebooks can be collected into groups as well.
Noteshelf has just hit version 5.0, and it has added a huge feature: typed text. If you prefer to take notes using a keyboard (or a particular situation calls for not using a stylus), Noteshelf has you covered. There are plenty of other new features, including another big one: the ability to use tags in your notebooks.
Notebook is still only $4 (US) in the App Store, and it is now even more useful for attorneys who want to dump the paper legal pad.
