Sony To Launch E Ink-based eBook In April

Holly Gates writes "Sony will launch an ebook based on E Ink technology in Japan in late April. The screen is about as big as half a paperback book and has a spatial resolution of ~170ppi. The device includes various edictionaries and audio playback functionality. I am a hardware engineer for E Ink by the way, but I figured slashdotters might be interested." An anonymous reader notes that it is supposed to "display over 10,000 pages on a single set of batteries."
