I like to read comics and was looking myself for some color eInk device but was put off by the price (€500 and more) with moderate color presentation.
So I opted for a genuine Tablet and found a
TCL Nxtpaper 11 for a steal (€199 at Amazon, just the tablet). There was also a package including cover and stylus (T-pen), but it was sold-out. The T-pen should be separately available but I could not find it anywhere. This week I saw an announcement for Nxtpaper 3.0 on a 14" device; TCL seems to continue this line of devices.
My device is about 11", solid build (aluminium frame), runs on Android 13, has 4Gb RAM and 128Gb storage (upgradeable to 1Tb via microSD), uses Nxtpaper 2.0 and claims to be an eInk alternative. There seems also to be versions with 4Gb RAM and 64Gb and 6Gb RAM and 256Gb. It has an 8000mA battery which can be fast charged via a Power Delivery capable charger. As the tablet supports Universal Stylus Initiative (USI 2.0), I could easily find a stylus alternative (Penoval Active Stylus USI 2.0).
I like the device and it works well for me to read my comics. The matte screen does hide fingerprints but you still can see them. The special Nxtpaper settings do work, but it is a personal taste whether it works for you. The battery lasts long enough for long readings, that is a plus, while there is plenty storage for huge files.
