I love and use Egress all the time for catching up on Blogs on my Pocket PC, I just sink up over my wireless network at home and then read when I've got a moment spare.
So now there are at least two Pocket PC RSS Readers that support Podcasting, check them both out - awesome!!
PS, At the risk of "egg sucking" if you are not that sure what a Podcast (or Blogcast or Videocast) is then check out http://en.wikipedia.org/wiki/Podcast, but putting it real simple it's just a downloadable MP3, WMA or WMV file with captured audio and or video which will hopefully entertain and info you and often published via RSS.
