Let’s start with the general apps - as a bonus, most of them are absolutely free!
1. AP Mobile News Network
Free. This is a great source for local news, world news, and more. There is even a category called “Wacky.”
2. NetNewsWire
Free. I use the desktop version of NetNewsWire for reading RSS feeds from a bunch of sites. This is the mobile version. It has a few bugs, but it syncs with the NewsGator feed and keeps all of your subscriptions in sync from computer to iPods.

3. Weatherbug
Free. Sure there is the built-in weather application, but I like Weatherbug better. It not only give mores information, but it provides up to the minute weather information, and you can set it up for more than on location.
4. Traffic
$1.99 My wife uses this app every morning to check the traffic report for her drive to work. It is extremely accurate, and even works with Google Maps to give you a view of the problem areas. You can set it to give reports within a certain mileage range from your location. This app is definitely better than sitting around waiting for the traffic report on TV.
