The Note Air series is focused on note-taking and document reading rather than tablet-style productivity. The writing feel is designed to mimic paper, making it popular among students and researchers.
The color version enables colored highlights, diagrams, and comics, although color resolution is lower than grayscale due to the Kaleido filter layer.
