$129 (about £83) popslate.com What is it? PopSlate is a case for your iPhone 6 that displays E ink images ‘popped’ over from your device to the reverse of the case. Powered by its own internal battery, PopSlate is designed to show photos or important information (like your calendar or flight boarding pass details) for use when your iPhone’s battery has hit zero. When’s it due? July 2015. Why are we excited? At the moment it can only display black and white images and can’t show notifications, but with further developments in the pipeline, it could become a genuinely useful case for displaying essential information without draining your battery.
