So my presumption only, is that its screen wouldn't be as kind on the eyes, if it isn't E-Ink, and I've found that to be important, especially as I get older.
My 10" Samsung Tablet, is great, has a great battery life (superior to any of my three E-Ink devices). But when it comes to reading on it, despite being very passable for that, I still want a kinder on my eyes 10" E-Ink device.
Is the Nxtpaper backlit or frontlit?

It can be OLED or LCD or QLED (Quantum dot red & green on LCD back lit by blue).
The top layer is micro-etched glass that has the lowest glare and reflectance of anything I've seen since the Victor 9000 / ACT Sirius 1 (matt nylon mesh) or a particular flat surface CRT monitor with a coating.
Eye strain is caused by glare/shine/reflections from a screen. That causes headaches because you unconsciously refocus on the further away reflected objects. It was established by 1980s.
A secondary much lesser issue is brightness. The peak white must not be brighter than local white objects in the ambient light.
A tertiary issue is the colour. No evidence that blue keeps you awake, but isn't relaxing. For mono, the amber beats green which beats white. Indoors you want to mimic the ambient light colour temperature. Only eink with no front lighting does that. The Nxtpaper devices have user adjustable colour temperature and no excess blue as with cheap backlights or frontlights.
The eink is only more restful than properly adjusted Nxtpaper if the ambient light is good enough to read by with no front light. Some eink front lights can vary the amount of amber.
The reading settings and most other settings on Nxtpaper are a gimmick. Most like eink in decent ambient light with front light off is sRGB and adjusted colour temperature and brightness to ambient levels. Bright front light on eink is inferior to Nxtpaper 2.0 or 3.0.
You would not know it's OLED or LCD (or which of those, because some use one and the other) when properly adjusted. It then just looks like high quality "coffee table" coloured print books.
The original Nxtpaper wasn't bright enough (turned up) for sunlight. The Nxtpaper 2.0 and 3.0 devices I have are. You'd only want auto brightness outside. Indoors it's best set manually to 9% to 16%, depending on ambient brightness.
I've never seen any gadget that did auto-brightness indoors properly (first deployed on late 1950s TVs). Nor decent auto-white-balance.
EDIT
[* In early 1980s we sold white mono screens for school computers, then bought them without CRTs and fitted green or amber CRTs. Most wanted the Amber when they saw it.]
