Battery life. It's a big advantage to some people. Maybe most people are OK charging every day, but a big minority aren't. Camping, multi day festivals, unplanned promiscuity, overnight business trip to someplace with different sockets. 24+ hr traveling (EG London to Sydney). Even outside of these, people ask for chargers all the time. Trade off is worth it to some people. Especially if they rarely do the things e-ink is is bad at like games and videos.
