Amazon on Wednesday unveiled a brand new device, the $290 Kindle Oasis, its eighth-generation Kindle e-reader. Billed as its thinnest and lightest e-redear yet, the Oasis weighs in at just 4.6 ounces and measures a remarkable 3.4 millimeters at its thinnest point, which is less than half the thickness of Apple's iPhone 6s at its smallest point.
Its dual-battery charging system lets you read for months without plugging in if you're using the Oasis with the official charging case. Without the case, the device's built-in battery provides up to two weeks of reading based on 30 minutes usage per day.
