I wonder what the battery duration would look like. If such a device lasts a day in "e-ink mode" (I know the term is not exactly correct), I would be perfectly content with it. Charging it once a day is not a bigge (over night?).

Let's call it "reflective mode". You see...the screen reflects
the light of outside sources in that mode, rather than transmitting
its own light. It's not "e-ink" or really anything like E-Ink, except for being reflective, which LCDs have done for many years before E-Ink existed.
The 160-hour figure is rather ridiculous, and highly, highly unlikely even with good low-power boards. 160 hours in standby
, which means the screen is off and the device is not actively in use, is possible.
