Another podcast I listen to a lot is Tech Chick Tips Although they can be hyper, they have some great resources. I find one or two new applications or sites that I like from listening to them. Anna and Helen are from Texas and are both teachers.
They also have a wiki for a list of their resources http://techchicktips.wikispaces.com/ Each podcast is about 30 to 40mins long, which does not take a long time to listen to. One viewer said listening to them on 2x speed can be difficult since they do talk very fast at time.
If you want to know some of the latest tips or tricks check them out... They also talk about iPhone/iPod apps.
And that is what I am listening to.
