    Verdict

    The Onyx Boox Nova Air 2 is a versatile 7.8-inch e-ink tablet featuring a high-resolution Carta HD display with 300 PPI and a dual-tone adjustable front light. Powered by an octa-core 2.0GHz processor, 3GB of LPDDR4X RAM, and 32GB of internal storage, it runs on Android 11 with full Google Play Store support, making it a capable device for both reading and productivity. Main pros include its exceptionally lightweight 235g aluminum-magnesium design, a responsive Wacom layer supporting 4,096 levels of pressure sensitivity for note-taking, and dual speakers for audio content. However, notable cons include the lack of a microSD card slot for expandable storage, the absence of a 3.5mm headphone jack, and no official water resistance rating.
