One of the most useful, convenient, and economical (i.e. usually free) products of this ongoing (and accelerating) information revolution is the podcast.
"Tivo for Radio". That is the apt description of podcasts provided on this episode of the Kennedy-Mighell Report. (If you want to really learn about podcasts, listen to the KM Report).
There are scores of great programs you can download and experience at your leisure. Many offer continuing legal education credit. Anticipating the technology objection, that is no excuse: If you have an IPod, you can get podcasts the same way you get music. Get your kid to set it up for you.
For those with other devices, Wikipedia has a great list of "podcatchers" (programs which can fetch and store these files). When you subscribe to a particular podcast or feed, new episodes will be available for delivery to your device or computer through a variety of methods.
For attorneys, some great sources of podcasts include the Legal Talk Network (which hosts the Kennedy-Mighell Report and Lawyer-2-Lawyer, the TWiT Netcast Network (host of This Week in Law), and Cordell Parvin's Law Consulting Coaching Podcast.
Another resource for attorneys is the ABA TechEZ Training Library, offering short presentations on ways to use technology tools effectively in your practice. (Is this technically a podcast, webinar, or online presentation? Immaterial. It is a resource I can access when I want it).
There are many other sources for great podcasts: NPR, TED, and the Long Now Foundation, to cite just a few examples.
