E-Readers are undergoing a resurgence in popularity and more new devices were released in 2019, than any other year. There were two different types of hardware, consumer grade e-readers such as the Kindle, Kobo, Nook and E-Notes such as the Onyx Boox MAX 3 and Likebook Ares.
Amazon released four new e-readers in 2019 – the Kindle Paperwhite 4, which now is waterproof, the Kindle Oasis 3 with warm light system, Kindle Basic with a new higher resolution panel and the Kindle Kids Edition with a multiyear warranty.
Barnes and Noble released the Nook Glowlight 7.8 this year and it was the first large screen e-reader. It was a large success for the bookseller, no pun intended.
