The AP news reader use to be one of my favorite apps, until its last upgrade. I do use USA Today and the ABC app. I previously enjoyed the simplicity of AP, but now it's messy and crashes often.
I like USA Today, since I can click on each section, and download the updated news in a few seconds. Then I can read the entire article when I am 'offline'. On 3G it works rather quickly. On my 3GS, it is almost instantaneous.
