I've been downloading TED Talks on my iPod. This is one video podcast I wish I'd gotten in on the ground floor.
Here is Michael Pollan, Omnivore's Dilemma author, talking about what's next. It's excellent. If the embedding doesn't work (and signs indicate it won't) check the page here - http://www.ted.com/talks/view/id/214
Don't know that TED is? Pay more attention.
The other three TED Talks that I'm unable to delete from the device are:
* Jaime Lerner - Sing a Song of Sustainable Cities (15:43)
* Ben Dunlap - The Story of a Passionate Life (19:08)
* David Gallo - Underwater Astonishments (6:01) (this one I shared with The Boys)
