While I agree it's a poor fit and pretty much just a crappy but flashy tech demo... the display is what it is, it doesn't have mandated suitable uses.

Other reflective display tech exists. For the most part they suffer from screen-dooring, extremely bad visibility angles, much worse contrast in bright light, or complete unavailability in the size or resolution that you want.

Eink may not have many options, but it is an option, in a market with few or zero competitors depending on what you want (largely because it's niche), and refresh rate is often a thing you can bend on. I would love to see more, but many of the companies I've seen trying to do this in the past no longer exist, or they're selling even more niche ruggedized laptops and nothing else (and they still look much worse than eink, though they have color and refresh rate). It seems to be slowly ramping back up though, so hopefully within the next few years we'll see more.
