E Ink has long been lauded as a versatile, universally legible display technology, making appearances in NOOK tablets, Amazon Kindle devices, and a couple of weird prototypes over the years.
Onyx International, a manufacturer of ebook readers, has evidently created a prototype smartphone – powered by Android – that uses a full E Ink display.
The phone you see above is apparently the only prototype of this device in existence (so far). While the specs aren't named, we can see that the device is running Android Gingerbread, and not without its issues. Of course, as a – presumably – unfinished device, bugs are to be expected.
