TechCrunch is reporting that it has seen a prototype of a next-generation Kindle Paperwhite that features a flush, glass screen and a more angular design thats more in line with Amazons recent Kindle HDX tablets. The new Paperwhite, reportedly codenamed Ice Wine, is expected to utilize that improved screen with improved typography — including a new custom font designed specifically for the device and perhaps the ability to reflow text with hyphenation. The new Paperwhite will also reportedly have a light sensor so that it can automatically adjust the screens brightness for ambient conditions.
