With all the styli floating around the Android tablet world, it was only a matter of time before someone made a really excellent notation app for pen-based input. That app is Papyrus, a long-term project from indie developer Steadfast Innovation. The free app introduced its first beta version today, and you can download it on the Google Play Store. While it's technically possible to use standard finger input in Papyrus, it's specifically designed for Android tablets running 3.0 or later with stylus input options.
