Some of Boox's smallest e-readers are about six inches, but the brand teased an even smaller Boox Picco, a mini e-reader with a 3.97-inch monochrome ePaper display, as part of a new Tile product line. Complete with a black-and-white e-paper display and E INK technology, the device promises a comfortable reading experience, day or night, and the option for enhanced storage with an SD card. While some mini e-readers only offer limited file support, if the Boox Picco can access the Google Play store, users will be able to download the Kindle, Kobo, and Libby apps.
Mini e-readers are emerging as a compact alternative to traditional e-readers and smartphones, with phone-sized devices offering the portability people want without sacrificing the paper-like, eye-friendly display that makes long reading sessions comfortable.
