I'm still exploring the 23 Mobile Things.  One of the things is hobbies.  There are a couple of good apps, including RoadNinja and ESPN ScoreCenter/ESPN SportsCenter.

Road Ninja would be great to use on the next road trip.  It gives you information about what is available at freeway or highway exits.  You will be able to get information on restaurants, hotels, shopping and gas stations.  The information on gas stations includes the price of gas!

The ESPN apps will let you check on current scores so you can keep up with your favorite team or sport.  ESPN ScoreCenter is only for Apple and ESPN SportsCenter is only for Android.
