I have bought my M92 after inspecting ipad4 which boasts of retina display with 264ppi. After discovery that ipad4's software rendering is still limited to 132ppi (see photo), I have realized that I will be satisfied with M92's 150ppi :-)
In the very beginning I was considering jetBook Color, but even its 204ppi was too little. Reasonable optimum for scanned books is 300ppi at bw colors. However, E-ink has 16 grayscale colors, therefore even 150ppi is satisfactory. Attached is my experiment with 10pt character "P" rendered at various ppi and color depth.
