Amazon is reportedly working on a new Kindle Paperwhite model, which should arrive at some point in early 2014, according to TechCrunch. The flagship feature of the new reading device is said to be a new high-resolution display that will have a 300 pixel-per-inch (ppi) density. The publication also reports that it has seen a prototype of the e-reader, which has a display made of matte glass instead of plastic and which seemed “flush with the edges” rather than recessed. In spite of using glass, the new device is lighter than its predecessor. Furthermore, the edges of the device will apparently include squeezable buttons that will provide some sort of haptic feedback when touched and would let users change pages.
