iNewsCaster looks like a mix between an RSS reader and an MP3 player. This clever combination allows you to follow listen toyour feeds on your export them to your iPod. We didn't really like the option to add feeds, because it gives you a whole list of preselected feeds instead of making it easy to add your own. You can still very easily create your own playlist, into which you can drag and drop feeds.
iNewsCaster can export feeds to iTunes, from where you'll be able to export them to your iPod. What about the sound quality, you'll ask? While sounding a bit metallic at times, the playback features works pretty well and are very easy to use. It's unfortunate that the audio editing tools are fairly limited though, and you can get tired of hearing the same voice reading off your feeds.
An original tool, although I personally prefer sticking to a simple RSS aggregator and reading my favorite feeds.
