The main differences between iPodder and FeederReader are that iPodder, as far as I know, is program that runs on a desktop (PC, MAC, linux) in which you specify feeds and it downloads those feeds periodically and stores them on the disk. You can then semi-automatically (maybe automatically?) transfer them to a listening device or storage card (in a card reader). Every morning, you can pick up the card and go. Every evening, I think you have to manually delete the podcasts that you've listened to.
FeederReader is a self-contained program that runs on the Pocket PC in which you specify feeds and it downloads them and their attached enclosures (if so selected).
These are different ways of listening to podcasts. I think the advantages of FeederReader are
1) Does not require a separate desktop machine,
2) integrated reading and listening, you can listen to podcasts while reading other feeds, and then tap an icon to "Show Playing" to see additional notes from the current podcast (if they are supplied by the podcast feed).
3) integrated file management, with one tap you can delete the current podcast and play the next one.
4) Can handle any enclosure that can be played on the Pocket PC, like video and pictures. And you can download additional players for additional enclosure types.
I think the integrated feel of the Pocket PC with the ability to optionally view notes from the podcast makes for a great experience. I download, listen, and delete every day. I have about 110 feeds and 10 podcast feeds on my 256KB SD Card (in an iPAQ 2215) and I use a combination of GPRS for the feed updates and ActiveSync for the podcast downloads. A better solution that some of my users have is a WiFi connection. One thing to watch out for is to get a storage card with a decent write speed. My VERY SLOW kingston card is just barely tolerable, but it did help me optimise the update process to get it as fast as possible on my slow card. On faster cards, I've heard that it updates great.
I would love to see a side-by-side comparison of iPodder, or any other podcatcher or RSS reader, and FeederReader. Please let me know directly if you do such a comparison. I would expect that in some cases, iPodder would be a better choice (if you have very little internet connectivity to your Pocket PC and if you have an always-on desktop connected to the internet). And I've worked hard to make reading and listening as easy as possible on FeederReader.
