In total, it
seems like I'll get 25 - 33 % more
words on the K3 screen, which is great for a few reasons: having to press the
page turn button less frequently (which is nice in itself) also means I should be able to read faster, and the battery will last longer, since e-Ink screens only use power when you change
pages (you should get about 10,000
page turns
per battery charge, regardless of how many
words are on each
page).
