If you're old school or a slow typist and prefer taking notes by hand then you should check out Papyrus.

You can use your finger or a stylus to make notes in a range of different colors and pen thickness, as well as add images and videos, and record audio. It's also possible to change the note background, export as a PDF, JPG or PNG image, and delete entire sections or erase individual words and characters.

Papyrus is easy and intuitive to use, and is the best handwriting note taking app out there.
