I do the New York Times crossword on my iPad. While it s a highly enjoyable way to pass time, I find the on-line version sometimes not quite up to the task, especially when the NYT runs one of their novelty puzzles. On the other hand, you get instant checking and scoring with the on-line version, a major plus.

The iPad is heavy, however, and the glowing screen causes eyestrain in low-light conditions. Consequently, it has never occurred to me to do the crossword in bed; it's an amusement for after breakfast on the kitchen sofa with the cat.
