One week after Amazon CEO Jeff Bezos dropped the hint of a new Kindle coming, it's finally here. The company announced the Kindle Oasis [1], the lightest, thinnest, and most impressive ereader yet.

Here are all the details on the Kindle Oasis:

• It weighs just 4.6 ounces, making it 20 percent lighter than any other Kindle.
• The Kindle's newest design is meant to rest in the center of your palm, instead of gripping it.
• The screen is the brightest ever — with 60 percent more LEDs.
• A leather cover in three colors, Black, Merlot, and Walnut, will now come with the Kindle.
• The leather cover recharges the Kindle as soon as it's connected. If both the Kindle and cover are unplugged, the cover will lose battery before the Kindle does.
• You can charge the cover and device at the same time, as long as each is plugged into its charging console.
• With just one charge, the Kindle Oasis's battery will last for more than two weeks. With the charging cover, it will last for more than nine weeks.
• A new hibernation mode will use the least amount of battery when the Kindle is not in use.
• It is not waterproof.
• It will be available in a WiFi model and WiFi with included 3G.
• The Kindle Oasis [2] will cost $290 for the WiFi model and $360 for the WiFi model and free 3G. Preorders begin today, and shipping starts on April 27.

The Kindle Oasis is a bold move for Amazon, a company that's become pretty synonymous with ereading, thanks to its Kindle products and app. This might be the product that finally converts old-school paperback readers to the Kindle Oasis. Look ahead for photos of the Kindle Oasis. If it doesn't suit your needs, Amazon does have other tablets [3] available that you can use the Kindle app on.
