Are e-ink writing tablets good for handwritten notes?

Yes, that's their core use case. The matte e-ink surface mimics paper and reduces glare and eye strain compared with a glossy LCD tablet. Among the candidates, the reMarkable line and the AINOTE devices are purpose-built note-takers, while the TCL NXTPAPER and BOOX models add full Android apps on top of paper-like displays. Just note that none of these picks carried independent expert testing in our data, so we leaned on verified-purchase ratings.
