Everyday users praise the device's portability, long battery life, clear color display for comics and manga, and the convenience of built-in audio, but complain about its relatively heavy chassis and inability to expand storage.
Professional reviewers commend the Note Air 4C for its vibrant Kaleido 3 color e-ink panel, robust octa-core processor, and full Android 13 ecosystem, noting that it delivers solid performance for document-heavy workflows. However, they point out that the lower color resolution and modest speaker quality prevent it from being a premium multimedia device, and the incremental upgrades over earlier models may not compel existing Boox owners to upgrade.
Everyday users love the tablet's lightweight feel, color display for comics and PDFs, and the precision stylus for note-taking, while repeatedly mentioning the trade-off of reduced color sharpness, average built-in audio, and the need to recharge more often during heavy use.
