The front lit E-Ink screen means it will work under all lighting conditions.

It boasts access to over 1,000,000 apps, but I wonder how the E-Ink refresh rate will work with them?

No camera. Even if the B/W display meant pictures would have to be viewed on another device to be viewed in color, a camera would have been perhaps a selling point.
All in all a very intriguing device. It will be interesting to see the owner's reviews when they begin appearing.
