Why this matters
What the Boox Note Air 2 still is in 2026
The Boox Note Air 2 launched in 2021 with a 10.3-inch Carta 1200 panel, the original Boox Pen 2, and Android 11. Four years and two successor generations later, the Note Air 4C and Note Air 5C have replaced it as Onyx’s mid-range writer, but the Note Air 2 keeps showing up in the buying conversation. Some readers want a mono-only e-ink writer at refurb prices; others land on the Note Air 2 because the Kaleido color panel on the 4C didn’t suit them. The question for both groups is whether a 2021 device still earns its place in 2026.
Short answer: yes, with caveats. The Note Air 2 still gets occasional Onyx firmware updates, which is unusual generosity for a four-year-old e-ink device. The mono Carta 1200 panel is the same generation that’s still in current mid-range Kindle Scribe and reMarkable 2 hardware, so the screen feels current. What’s dated is the Android 11 base; some 2026 apps require Android 12 or higher. For Kindle, OneNote, and the boox-native reading and writing flow, that doesn’t matter. For newer Android apps, it can. Our wider Onyx Boox 2026 lineup piece places the Note Air 2 in context against current models.
vs the 4C
Note Air 2 vs Note Air 4C: where the four years matter
| Spec | Note Air 2 (2021) | Note Air 4C (2024) |
|---|---|---|
| Screen | 10.3″ Carta 1200, mono only | 10.3″ Kaleido 3 + Carta 1200, color |
| Pen | Boox Pen 2, no eraser button | Boox Pen Plus, eraser button |
| Android | Android 11 | Android 13 |
| Storage | 64GB | 64GB |
| RAM | 4GB | 6GB |
| Weight | 420g | 430g |
| Price (new / refurb) | ~$250 refurb | $499 new |
The headline differences are the Kaleido 3 color panel and Android 13 on the 4C. For users who don’t care about color (most note-takers in our experience), the Note Air 2 closes the gap surprisingly well. The pen-on-screen feel is close enough that we couldn’t reliably tell the two apart in blind tests; the eraser button on the 4C’s Pen Plus is the one ergonomic improvement that matters. The Android version gap will widen over time as more apps require Android 12 minimum, but as of 2026 most reading and writing apps still target Android 11.
Who it suits
Who the Boox Note Air 2 still suits in 2026
Three reader types still benefit from a Boox Note Air 2 over a newer device. First, mono-only writers who’d rather pay $250 for a refurbished 10-inch e-ink notebook than $499 for a color one they won’t use. Second, Android-app users whose primary apps (Kindle, OneNote, Libby, Pocket) all run on Android 11 without issue. Third, buyers who tried a Kaleido color panel on the 4C and found the slight tint or muted colors annoying; mono e-ink remains crisper for text and writing.
Three reader types should skip the Note Air 2. First, anyone wanting color rendering for status-coded planners or color-aware PDFs; the mono panel can’t deliver that. Second, anyone running newer Android apps that target Android 12+ or require recent security patches. Third, anyone wanting future-proofing past 2027; Onyx will stop firmware updates eventually, and the Note Air 2 is closer to that cutoff than newer hardware.
The Boox Note Air 2 in 2026 is a $250 refurbished mono e-ink writer that competes well against the $499 Note Air 4C, if you don’t need color.What we found
Where to buy
Where to buy one in 2026
The Note Air 2 is no longer sold new through the official Onyx store; new stock ran out in late 2024 when the 4C launched. The current paths to a Note Air 2 are: Onyx’s official refurbished program (best for warranty), Amazon used or refurbished listings (faster shipping, less consistent condition), and eBay (lowest prices, no warranty). Refurb prices stabilised around $250 in 2026; expect to pay $200 to $280 depending on condition. Our wider Boox refurbished 2026 piece covers the buying mechanics across all paths.
What to verify before buying: that the seller is shipping the Note Air 2 specifically (not the original Note Air or Note Air 3 by mistake), that the device firmware is updateable to the latest Onyx release (some refurbs ship with stale firmware), and that the Boox Pen 2 is included. Replacement Boox Pen 2 units run $50 to $70 standalone, which closes some of the refurb-price gap.
