TechCrunch reported that Amazon intends to update its Paperwhite e-book reader for the spring 2014 release. The tech company plans to improve the screen resolution from 212 ppi to 300 ppi. The weight of the device will supposedly be cut down as well. Amazon also reportedly wants to improve the typography with a customized font, provide “squeezable” buttons for haptic feedback, and add ambient light sensors to improve auto brightness adjustment.
