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."
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.
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.
$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.
