He will definitely not be taking notes on the reader or other fancy things like that. Now that I think about it, I am not even sure that he would use the touchscreen ability if buttons allow to do everything too easily (is that the only difference with the pocketbook 902?).
So indeed if it comes down to 220€ vs 360€ for a bit more contrast, all other pertinent requirements in this case being constant, the pocketbook seems more attractive. You guys are really, really helpful to make a choice, thank you.
