    Verdict

    The Onyx Boox Nova 3 Color is a versatile 7.8-inch e-reader featuring an E Ink Kaleido Plus screen that displays 4,096 colors at 100 ppi and crisp black-and-white text at 300 ppi. Powered by a Qualcomm Snapdragon 636 octa-core processor, 3GB of RAM, and 32GB of internal storage, it runs on Android 10, allowing full access to the Google Play Store for various reading and productivity apps. Main pros include its responsive Wacom stylus support for high-precision note-taking, sunlight-readable display, and dual-band Wi-Fi and Bluetooth 5.0 connectivity for audiobooks. However, significant cons include relatively muted color saturation compared to LCD tablets, a dim screen that often requires the front light, and occasional ghosting during content refreshes.
