Perfect dictionary for translation and regular work
This is a great all-around dictionary. It not only does a great job of E-F / F-E, but also helps with masculine / feminine, definitions through extensive use of word forms (i.e. putting the word into various expressions) and has full verb conjugation tables (there is a conjugate button on the verb pages). I also have the Larousse Illustré but rarely use it because this one does the trick.
It even works great on the iPad 1 my kids use, albeit a bit slow compared to my Air.
