Query: Not Very Literate

I use this mostly for crossword puzzles, and I found that it's less literate than I am. If I don't know the spelling or definition of a word, often it won't either. I had a similar product back in the '80s. It cost more at the time, but was far better. Also, the cover on this one is difficult to open, and the keypad is hard to use.
