Polish distributor Arta Tech has been showing off some prototypes of a new device, the MIDIA InkPhone, developed by Chinese e-reader company, Onyx.  The InkPhone is a hybrid between an e-reader and a mobile phone, designed as a bare-bones back-to-basics device with making calls and reading text being its main functions, with the main selling point being its lengthy battery life.  The solo E-ink display is designed to slowly sip power, allowing the InkPhone to supposedly last more than two weeks on a single charge of its 1,800mAh battery.  This seems like a perfect choice for people who need long battery life (like hikers or backpackers) or those who are simply looking for an e-reader that can also make calls.  Since there is no need for high resolution display for the content, Onyx can cut down on the internals and price.  There's also no camera and only 4gb of onboard storage, but a microSD slot helps that a bit.  

According to Engadget, the phone responds very well on the reader side and is as smooth and responsive as the kindle app for smartphones. However, the phone does have some other issues, like taking up to 20 seconds to respond to commands like swiping pages on the home screen, and the phone cannot use any android apps unless the APK is installed by the owner.  If you are interested in trying one out, the InkPhone will come out in April in Germany and Poland for €140 ($195), and will be available on Amazon for everyone else.
