We have seen some crazy E-ink concepts in the past, including phones with two screens. Not everyone is ready to go with something like that. Thanks to the InkCase, you can add a second E-ink display to your phone. It uses Bluetooth 4.0 to connect with your phone, so it won’t drain its battery. The InkCase displays any picture that you like on the back of your phone. You can also display useful information such as weather forecasts and your daily to do list.
InkCase is available to iPhone and Samsung Galaxy users. It is lightweight and easy on the eye. InkCase will display information from the apps made by Oaxis for now. But the idea is quite interesting. How popular something like this will be is anybody’s guess though.[source] [via]
