That would be, of course, if for 93 hours one played a 30Hz flashing B-W-B-W... The average dot switch, on a binary (B/W) threshold, on normal video, is probably well less than every second. A value between 1'000 and 10'000 hours is more realistic. The technology was not born for this use.

Nonetheless, the lifetime values one can find do not seem to be precise and reliable (that of 10 million is one piece of reported official information and not the only one). Having tests would be better, I am not sure how much these speculations can be trusted. Anyway, given the presence of EPD based smartphones in the market, together with the monitors, information will have to come out of users' experience.
