I did a "skew correction" of that angled image to straighten it out-- the display aspect is right around 3:5 (the 5 inch e-ink readers are 3:4.) Unless I'm screwing up my basic high school math (disclaimer: I may be screwing up my basic high school math) this gives the unit a screen size of around 2.57 x 4.28 inches vs. 3 x 4 inches on e-ink displays.
