    Verdict

    The Onyx Boox Note Air 3 is a 10.3-inch monochrome e-ink tablet featuring a Carta 1200 display with 227 PPI resolution and a paper-like etched glass surface. Powered by a 2.4GHz octa-core processor, 4GB of RAM, and 64GB of expandable storage, it runs on Android 12 with full Google Play Store access for third-party apps. Main pros include its versatile software ecosystem, excellent note-taking experience with the included 4,096-pressure-level stylus, and a premium, slim 5.8mm aluminum-magnesium build. However, notable cons include its lower pixel density compared to some competitors, the lack of an IP rating for water resistance, and relatively weak onboard speakers.
