I like the Kobo Mini because of its portability; it fits perfectly in my purse. I was fortunate enough to pick it up for a steal at $38 during a big sale, otherwise I probably wouldn't have been willing to pay the usual $80 for it. The battery life is fantastic, as long as the WiFi is turned off. I have to admit that the mini games are kind of a novel distraction, too, since I love Sudoku.
