For anyone that does mostly office work/paperwork, yes.

For everyone else, not so much. The refresh on eink displays is often orders if magnitude longer than with traditional displays, so forget watching YouTube or something, on a display like this.

Almost every display in existence does 60+ Hz. This is required for light emitting displays, since humans generally see 60Hz flickers of light as solid light (consistently on), so they have to run at that frequency to produce an image that doesn't look like it's flickering on and off.

With eink, it's only reflecting light, not emitting it, so update times can be and are, a lot slower. Due to the mechanism that's bringing the relevant pigments to the surface, which isn't fast, you'll see these displays measured more in seconds per frame than frames per second. Partial updates of the screen can be done much faster, but full frame updates can take several seconds. Eg, adding one more character (while typing a document), is a quick update and can happen many times per second on most eink displays, changing the whole screen, which happens often in video content, takes 1+ second(s) to complete.

So for the office drones that deal with email and text files all day, this is great. For any media content including TV, movies and video games, this is utterly useless.
