OneNote's drawing functions are criticized for lacking essential features like curves, making it inadequate for detailed note-taking in subjects like physics and mathematics. Users express a preference for pen and paper for on-the-spot note-taking due to the efficiency of writing equations and diagrams. Some find typing plain text faster but struggle with diagram creation. Alternatives like tablets with stylus support are considered, with specific models such as the Lenovo X series tablet and Wacom Bamboo pen being mentioned for their functionality and versatility. Additionally, using a camera to capture whiteboard notes is suggested as a way to avoid distraction during lectures. Overall, there is a strong inclination towards finding better software or hardware solutions to enhance the note-taking experience.
