I'm just going to put it right out there: I love my Kindle. The battery life lasts for weeks on a single charge and it's so slim that I can carry Tolstoy around with me in my PS11. Needless to say, the recent arrival of the Kindle Oasis — Amazon's latest edition to the Kindle e-book family — had me at page one.  

Amazon's Kindle Oasis

Even as the e-book libary on Amazon continues to grow, the Kindle itself seems to be getting slimmer. Weighing less than 150 grams, the 3.4mm-thick Kindle Oasis is the tiniest member of the family. Thankfully, the 6-inch screen remains, keeping the reading experience easy on the eye.  

Removable charging covers for Amazon's Kindle Oasis

However, the price tag might put some off. At USD 289, it is also the most expensive Kindle to date. With that money, you could get yourself four entry-level Kindles, but you certainly wouldn't get its most sophisticated built-in light function that allows you to read comfortably under all types of lighting. Moreover, a new dual-battery charging system enables the accompanying cover to double up as a charger for your Kindle, so your Kindle will run for months instead of weeks without needing to juice up again. The removable charging cover isn't too shabby either. Made of leather, it comes in your choice of black, merlot, or walnut.
