These are what I follow on RSS: Engadget (including their sister sites for Mobile and HD) Gizmodo
Engadget (including mobile and HD) has about 3 audio podcasts. The main Endgadget podcast is well done. The mobile one is OK. Gdgt is run by the founders of Endgadget and they are VERY smart. I also like Gadgettes and Buzz Out Loud. They're entertaining as well. GeekBriefTV also has some interesting stuff once in a while.
