Somebody's review here:
I don't use all of its features. Mainly I use the daily readings and the Bible. I can read the Bible in bed at night without having to turn off the lights when I'm ready to call it quits (because the lights are already off). No need to carry around the pocket New Testament; I have the whole New American Bible there in my pocket. Sad to say, though, Soduku gets more attention from me. Still, I open the Bible sometimes.
It also puts some of the Vatican documents at your fingertips. Also some prayers, some in Latin if you're into that. Anyhow, check it out.
