I guess the dictionary feature is a good feature, but, when I used to read books, I never took a dictionary with me and looked up words. So with the 505 , I don't miss the dictionary feature. But who knows, if I had it, I might use it. I hardly use it on my computer either, but I could. I guess it depends on type book you are reading. Now if I was learning a language , yeah, sure would be helpful. Or learning a new subject with NEW terms, medical for instance, yeah, medical dictionary would be helpful.
