I have a few podcasts I regularly listen to relating to the tech industry. Here are my favorite ways of catching up with the tech world:

1. This Week In Tech - Leo Laporte and a motley assortment of guests discuss the weekly tech news.
   
   
2. Buzz Out Loud - The amazing Tom Merritt and Molly Wood along with others discuss Tech news daily.
3. Security Now - Steve Gibson and Leo Laporte talk computer security.
4. Windows Weekly - Leo Laporte and Paul Thurrott talk about Microsoft products and Paul's obsession with Modern Warfare 2.
5. Cranky Geeks - John C. Dvorak and his crew of cranks give a different perspective on the weekly tech news.

I have a few others I listen to from time to time but these are the five I listen to the most.  Check them out on iTunes or visit their websites to have a listen I think you will enjoy them.
