Dubbed the Kindle Oasis, the reader is 30 per cent thinner on average and over 20 per cent  lighter than any other Kindle. It has a dual-battery charging system provides the longest battery life of any Kindle and a its removable leather charging cover lets you read for months without plugging in

The Kindle has been around for eight years and the Kindle Oasis is the eighth generation. Amazon siad that it is designed for extended reading sessions—with an entirely reimagined shape,

Kindle Oasis introduces a new dual-battery system—as soon as you connect the cover to Kindle Oasis, the battery in the cover begins recharging Kindle Oasis automatically. The battery in the cover uses a custom cell architecture that optimizes power and energy while keeping an incredibly small and light form factor and delivering months of battery life. You can charge the device and cover simultaneously while both are snapped together and plugged in. Plus, a new hibernation mode minimizes power consumption when your Kindle is inactive.

The included charging cover is made of high-quality leather and is available in black, merlot, or walnut. The cover opens like a book and fits closely around the bezel, waking Kindle Oasis when opened and putting it to sleep when closed. Twelve magnets form a secure and solid attachment between the device and cover, while ensuring it is easy to detach when you choose to read without the cover.

It also has a Next Generation Paperwhite Display. It is still 300 ppi Paperwhite but has a redesigned built-in front light features 60 per cent more LEDs for making it the brightest Kindle display so far. The new Paperwhite display on Oasis is the first Kindle display using a 200 micron display backplane combined with a custom cover glass engineered from chemically-reinforced glass.

Still the price makes this new Kindle a little pricey when you can get a basic one for just $80. The Kindle Paperwhite, the most popular and best-selling Kindle, features a high-resolution display and an adjustable front light, just $119.99.Still it is the thinnest and being thin and light is important if you have to read a lot.  The only problem I have with the kindle is the screen size and the fact that a lot of the text books have formating errors and sometimes come with diagrams and boxes missing.
