It's one of those things you wish you started earlier.  I used to listen to mp3 music or podcast programs on my laptop and never really felt the need for an iPod.  Well...after having used it for a few months now, I can not live without it - I now completely understand this new iPod & podcasting culture.  Since I travel much more with my new job, iPod became a natural travelling companion keeping me company on the road especially in planes and airports.

Many communications & training programs at Sun are podcasted.  Two of my favorite ones are innovating@sun(external) & geekspeak(internal).  I also started wine studying(or tasting ) recently and wine for newbies podcasting is helping me tremendously.

You should really try the iPod, but more importantly experience the abundance of podcasts out there ...
