We don’t see a whole lot of exciting e-readers these days. But that does not mean e-paper devices are dying. Take the PocketBook CoverReader for instance: it is an awesome case that adds a secondary display to your smartphone. Designed specifically for the Samsung Galaxy S4, the case has a 4.3″ E-ink screen on the inside of the cover. You will be able to see text and images from your phone on it. The Share button within certain Android apps enables you to view documents on your CoverReader. You can even use this case to keep up with your calls and messages.
You can pick one of these up for around $100 at this time. I would love to be able to buy one for my iPad though.
