The new software of Kindle Paperwhite comes integrated with Goodreads, a book lovers' community that Amazon acquired earlier this year. This new feature will allow Kindle owners to see what their friends are reading, share highlights, and rate the books they read with other Goodreads users, all from their Kindle.
In addition, the models offer built-in parental controls through a feature called FreeTime. It allows parents hand-select books for the kids to read, and hand out achievement badges when they hit reading milestones.
