I am reading a study that compares ease and effectiveness of ready an ebook versus a conventional book. The ebook doesn't compare favorably when it comes to comprehension or eye strain. The thing is they do not specify the screen type (front lit, back lit, e-ink?). Does anyone know what sort of reader this is?
