As it happens I am a big fan of the TWiT network and the This Week in Tech show in particular. I was listening to the podcast while walking today and stopped in complete surprise when Patrick started to talk about Scenic Map. I have the YouTube clip above set to play where Patrick begins to discuss the app.
TWiT has many other great weekly shows which iOS users will be interested in. In particular there is iPad Today and Mac Break Weekly. Patrick Norton has his own show called This Week in Computer Hardware. Here are a couple of links for the TWiT network if you would like to watch the shows. You can also subscribe to the pod casts in either audio or video formats on iTunes.
