There’s a choice of E Ink refresh speeds on offer, from the infrequent pages turns of ‘normal’ to the ultra-quick, video-capable X mode – although ‘speed’ and ‘A2’ are the ones to use for clear, concise-looking text without any ghosting (something evident in ‘normal’ mode). While this e-reader doesn’t include all the features you’d expect of a tablet, it’s does the job for browsing the web and using day-to-day apps – although those looking for a device on which to predominantly watch video content should look elsewhere. You can record audios, convert handwritten notes, sync the notes to the cloud, and share them in various ways with your colleagues.

Third-party pen-based apps fare more poorly, with unusably long lag (as I've seen on other Onyx tablets). The added benefit of Android has the same effect on the utility of this tablet as Red Bull on people's forelimbs. Anecdotally, after four days' worth of light testing with some reading, sketching, and taking notes, the 3,000mAh Note Air 2 still had 58% of its battery left.The reader has an additional ASAHI protective glass that protects the screen from damages when actively used. This means that the NA2+ is very versatile; you can use it in dark environments, listen to audiobooks, record voice notes etc. Despite running a customized version of Android 11, the core interface looks nothing like an Android phone or tablet.

There are no ports or buttons on the top, bottom or right sides of the tablet, while the left side sports the power button and USB-C port, as well as the loudspeaker. Some mention that the app that comes with it is easy to use and can export to Onenote and that the magnet design allows for easy attachment of the stylus. The Onyx Boox Note Air 2 Plus is a tablet and e-reader in one, arriving with a Boox Pine Green stylus with which you can doodle and take notes as you read.

Unlike the ReMarkable 2 and Kindle Scribe, therefore, you can’t charge it while it’s protected which is frustrating. Yet another strength of the Onyx platform is that you can read in whatever app you prefer, including the Kindle app. You can manually control both warm and cool backlights, and this is a key differentiator for Onyx's tablet line.
