Onyx Boox Note Air 4 C review: This e-reader is thinner than the S25 Ultra and has better battery life


Onyx Boox continues down the path of refinement.

Onyx Boox outfitted the Note Air 4C with an upgraded Kaleido 3 color E Ink panel which delivers better brightness and contrast levels, as well as a higher screen refresh rate. Frankly speaking, beyond the menial hardware upgrade such as the faster processor and newer Bluetooth chip, there's not a lot there to justify buying the Note Air 4 C over its predecessor. In addition to a wonderful built-in e-reader with exhaustive options, this Android tablet also functions as a spectacular note-taking device with native OCR.
