The Nook has competition with e-book readers like Amazon's Kindle and the Kobo Aura. Each e-book reader has its own advantages in terms of features and usability.
Amazon's Kindle features several different variations, including the Voyage and Paperwhite. The Paperwhite features a back-lit screen that gives each page an easy-to-read, contrast-rich look, notes Digital Trends. The text pops out while the backlight does not put too much strain on the eyes.
The Kobo Aura is a step toward innovation and features a waterproof frame. This e-book reader is designed for customers who like to read books while they bathe. The frame is also light and it features a contrast-rich display for easy-to-read pages, notes PC Magazine.
