That said, it won't hold as much of a charge as
a typical eInk device (i.e. Kobo, Sony, or the famous Kindle) which can generally hold a charge for reading for weeks (I've heard 2 - 3 weeks is typical, whereas mine lasts within about 1.5 weeks), whereas this would require (in typical conditions) daily charges.
Apart from continuously discharging, I understand it's supposed to be extremely similar to
eInk displays, which suggests it would perform extremely well for a
typical reading
device.
