My husband's got a new hobby—doing the NYT crossword on his iPod touch. He's getting close to finishing a Monday puzzle, and he insists that he likes doing it his way and has no need to read my book, How to Conquer the New York Times Crossword Puzzle. I think he might learn something if he read it. What say you? Should he continue slogging through the puzzles, learning at his own pace, or should he concede that his wife has knowledge that might benefit him?
