This phone is running Android 2.3 Gingerbread on a 1GHz CPU with 512MB RAM, a microSD card slot, Wifi, Bluetooth, and support for EDGE networks. Unlike the Yotaphone, there's no LCD screen. There's also no camera, but given the limitations of the E-ink screen I don't think you would want to take photos with it anyway.
This smartphone was developed by Onyx, but it's being shown off this week by Arta Tech. This Polish firm is a local retail partner for Onyx, and they have committed to releasing the Midia InkPhone in Poland.
There's no word on the retail price or release date, but I have learned that Arta Tech initially announced this phone back in December 2013. This story only crossed my desk this morning when Engadget got to play with the InkPhone (those lucky bastards).
Engadget says that this phone will ship with only 4GB Flash storage and a Rockchip CPU.
They don't have any details on the price, but they did repeat the detail that the InkPhone should run for more than two weeks on a single charge of its 1.8Ah battery. They also posted a gallery of 9 photos. I can't see them for some reason, but you may want to check them out.
Update: Engadget is now reporting that the InkPhone is expected to be available in Germany and Poland at some point in April. It'll be priced at around €140 ($195).
But even though I can't see those photos I do have a video I can share. Charbax got a look at this smartphone back in October:
