iFeedPod downloads RSS/Atom feeds to your iPod
iFeedPod is a cool little app that downloads RSS and Atom feeds to your iPod. Just add your favorite feeds to iFeedPod—OPML import is supported—and click on Sync and it'll copy your feeds' contents to your iPod in the form of notes. I can see this working great for some feeds and not so well for others. iFeedPod is free and unfortunately only available for Mac OS X.
