Once the novelty wears off, the device settles into daily use rather than staying a novelty. Owners describe reading during commutes, chores, work downtime, and before bed, treating it as a replacement for phone scrolling rather than a special-occasion gadget. Font customization and font size preference come up often as small things people configured once and then stopped thinking about, which owners are largely happy with.
Screen size and app usability are the areas people are split on. Some like the size for portability and find the reading app fine as-is; others find the screen small for their needs or run into friction with syncing and app features, occasionally switching to alternative reading software to get more control. These aren't universal complaints, but they're common enough that expectations should be set going in rather than discovered later.
