I usually download a book or two and some games that don't require internet access onto my phone. I used to bring a book, but my phone phone is lighter and has more options. Games that don't require internet access usually cost a couple bucks, but it is worth it. My favorites are Limbo, Brain It On!, and I believe the original Plants Vs. Zombies doesn't require internet. My phone has become the ultimate multi-use tool for enjoyment purposes in the backcountry.
