Well, they say nothing in life is free. I will suggest that this is one of the exceptions to that rule.
A while ago a close friend of mine and fellow photographer asked me if I had been following the TWIP podcast. I was like "TWHAT"? He said that if I went to iTunes and did a search under the podcasts I would find it, and it is FREE!
Well I downloaded a few of the TWIP podcasts and started listening to them on the way to work and back (my iPhone can play through my car stereo). I can't believe what an excellent show these guys produce. The information is golden, and the presentation is light-hearted and impactful. You can really tell that these gear heads enjoy talking about photography, and they definitely know what the heck they are talking about. All of them are high-end professionals including Fred Johnson from Adobe and Scott Bourne the author of four photo books.
If you even have a slight interest in photography I highly recommend that you get hooked on TWIP podcasts. Also, their blog is a mecca of information on anything from the latest Nikon and Canon, as well as other manufacturer product news to general photography tips and tricks, information on new products and advice for photographers new and old.
