Resolution : 600 x 1024 pixels
Screen Size : Vizplex™ 7.1 inches

Note that, as it looked from the photos of the unit, the aspect ratio is not the 3:4 one you have on other units. So the 7.1 inch figure makes it seem "more larger" than it actually is. This unit (doing a little high school math) will have a screen size of roughly 3.6 by 6.1 inches. But a "real" 7.1 inch screen-- meaning one keeping the 3:4 aspect ratio of other e-paper readers-- would have a resolution of 768x1024 and a screen size of 4.6 by 6.1 inches. So you are losing a full inch of screen width from what is implied by the listed diagonal measurement.
