Podcasts are great for keeping up to date, getting new ideas and generally helping you to feel connected with the rest of the geek community. Much less effort than reading a book, particularly with subjects that you're not even sure you're interested in yet, and you can listen to them on your way to work.

The quality of some of the podcasts out there is truly fantastic. Here's what you'll find on my iPod:

.net General Programming

• .NET Rocks! - The original .net show. Been around for years and still one of the best.
  http://www.dotnetrocks.com/
• Hanselminutes - From the great Scott Hanselman.

.net UI and UX

• pixel8 - Craig Shoemaker focuses on the user end of development.

General Software Engineering

• Stack Overflow - Jeff Atwood and Joel Spolsky the creators of stackoverflow.com discuss Stackoverflow (a lot) and everything else that effects the life of a developer.

That's all I can manage on my commute to work. If you've got any suggestions let me know and (if I like them enough to subscribe myself) I'll add them to the list.
