The Kindle Oasis is the latest and greatest in the Kindle e-reader family. The feather weight design is 20% lighter and 30% thinner than any other Kindle. With a new ergonomic design and higher resolution it's both easier on your eyes and hand when used for long periods. The Oasis comes with a leather cover with an in-built battery that will keep you going when the device battery dies, giving you literally months of battery life.
