Amazon has refreshed its Kindle Paperwhite device, whose screen now has a 300-pixel-per-inch resolution, a new “Bookerly” font, and a $119 price. The device is available for pre-order and ships on June 30. Oyster has launched Lumin, a new feature designed to improve the quality of the in-app reading experience by automatically adjusting to the natural sunlight outside based on the time of day and the user’s location. The company says that Lumin “gradually filters the blue light from your screen, replacing it with a warm, soft amber light” as the sun sets.
