Not that trash Kaleido faux-color e-ink, very nice.
This may be the first legitimate color e-ink tablet with good (EMR; see: S-Pen, Wacom, old style Thinkpad) pen input.

Perhaps something from the Universal Stylus Initiative?
That said, due to the fact that it does have an eraser, I would still guess that it is EMR but probably with a softer tip (e.g., the galaxy folds had special pens; other emr pens are "compatible", but might damage the crease, so they are not officially compatible).
