I assume you are native speaker, in Hungarian I understand an English word quite quickly, in explanation I have to think more, that is why I prefer the bilingual first, but if a word is not found or its meaning still unclear, I can go to the other. (BTW I also had the 1913 dictionary which was useful reading Alvin Maker series
) Actually with the 3.11 update the stock firmware is better in this sense, I can select which dictionary is default by book But it still doesn't beat koreader overall
