I'll add an ongoing link in my right side column for this item but for those who are interested in listening to podcasts while out and about, I point out that Mp3 flash players now are getting very cheap--say under $45. Because you can use them for transferring any file from computer to computer they're not a bad investment even if you only listen to Mp3 audio occasionally.
But a new program developed in Germany -- Podcatcher on a stick -- is a great way to get into the podcast lifestyle.
This is a program you download and operate from any Mp3 player (except iPod) so that you can download your audio from any computer by simply plugging the player into a USB port. So whether its at university or at work or home, just load up with audio wherever you are from the nearest pc and stick it in your ear.
