@bjones: WOW !! It's nearly exactly what I was looking for but I need the french dictionary and tactile could help
... I'll look if it's possible to install other dictionnay
@EA: great too. I like the kindle, I'll check too for those dictionaries.
If somebody else has a ebook reader with great translation habilities and want to share about it. :-D
