BOOX Note Air5 C
no budget ceiling
The safest big-screen pick when you don't know your priorities — 10 sources converge: 10.3-inch Kaleido 3 color, Android 15 with Google Play, stylus and warm frontlight in the box.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
The color panel is dim. Kaleido 3 renders color at ~150 ppi against 300 ppi in black-and-white and visibly darkens the screen, which is why the warm frontlight isn't optional on this device. Fast refresh also costs battery life, and the bundled stylus is overly long.
Dealbreaker? Runner-up №2 is a 300-ppi mono A4 page with no color trade-off ↓

Traps — this verdict avoids
Why the BOOX Note Air5 C is right for you
It avoids every trap below — and for just me, no budget cap, it is the pick because it delivers:
Color halves your resolution
Kaleido 3 and Gallery 3 panels render color at ~150 ppi against 300 ppi in black-and-white, and they visibly darken the screen — which is why a frontlight is effectively mandatory on every color model. Buy color only if you will actually use it.
Closed boxes stay closed
reMarkable, Kindle Scribe, Kobo Elipsa and Supernote install zero third-party apps — no Google Play, no browser, no Kindle-on-Kobo. Only Onyx Boox tablets run an open Android ecosystem. If app support matters at all, the field narrows to Boox.
"Large" rarely means A4
Most US listings are 10.2-11.8 inch, not page-sized. True A4 is the 13.3-inch class, it starts around $630, and Onyx Boox is effectively the only vendor selling it in the US. Sizing by the marketing word costs you a full page of paper.
