Once the novelty wears off, what stays is the habit. Owners describe reading in the gaps of the day (waiting rooms, commutes, fitting rooms) because the device is small enough to always be with them, and heavy books no longer get left at home. Font customization is a quiet favourite: nearly everyone who mentioned it liked being able to set type the way they want, and most who talked about pace or volume said they get through more books than before.
The adjustments are around power and the display. Battery life splits owners roughly down the middle, with more negative than positive accounts; some have gone to some lengths to cut drain when the device is idle. Screen quality and screen size also divide people, with a slight lean against the size. The companion app is mostly well regarded, though a few found it awkward.
