Since getting a car again, being faced with a 30-40 min commute each morning and investing in a Griffin iTrip Autopilot to get around the fact that the Polo doesn’t have an iPod connection, nor audio-in (shame!) I’ve been listening to a fair few podcasts lately.
On very high rotation are the excellent podcasts produced by Dan Benjamin’s 5by5, particularly the Back to Work show with Merlin Mann and The Talk Show with John Gruber. The first one because I’m going through a bit of a GTD phase and have found it to include a boatload of helpful nuggets to get me a little more motivated and organised; the second to hear some great discussions around all things tech.
If you’re into this kind of stuff, I definitely recommend listening in.
