■ The catch — co-equal billing, always
The color is the compromise. Kaleido 3 shows 4,096 colors at 150 PPI — half the 300 PPI of the monochrome layer — so colors look muted next to any LCD and text is softer in color mode. And the pen isn't the best in the family: Boox's own $400 Go 10.3 writes better, and reMarkable's Paper Pro better still at 12 ms latency. You're paying $530 for apps and versatility, not for the sharpest screen.

Color halves your resolution
Kaleido 3 renders color at 150 PPI — half the 300 PPI of the monochrome layer, so text is visibly softer in color mode and the 4,096-color palette looks muted next to any LCD. Buy color only if you actually need it.
The newer model writes worse
The Go 10.3 Gen II costs $20 more and dropped Wacom EMR for an active stylus — reviewers call the pen feel a regression. The original Go 10.3 is still the note-taker's buy.
reMarkable and Supernote aren't Android
Both run proprietary operating systems with zero third-party apps — no Google Play, no Kindle, no OneNote, no Notion. If app support matters at all, Boox is the only option in this category.
