The SmartTech podcast is posted on Sunday morning twice a month. If you subscribe, you will automatically get every episode for free.
I would also suggest that you use a podcast application on your iPhone or Android phone. I use Downcast. Another popular one is Instacast. Both are the same price.
These applications make discovering, subscribing, and listening to podcasts so much easier. The biggest advantage is that you don’t have to load iTunes on your computer, subscribe, and then manually sync to your phone. You can do the whole thing from within Downcast. They also automatically update your podcasts every time a new episode is released.
Just click on the episode title to go to that podcast where you can see the show show notes and listen to the episode.
