By the way, the iPod-in-car setup is working out great for the commute. I love having what is essentially a portable TiVo for public radio.
Of all the shows I'm listening to lately, the highlight has definitely been Radio Lab. It appears to have been a limited run series, with just two seasons of a half dozen shows each. But it's really brilliant. Dear Jad, make more!
I'm afraid if I were to try to describe it, I'd have a hard time distinguishing it from This American Life (“each week we have a theme…”). TAL is usually pretty good too, but Radio Lab is something altogether different. The image of a goat perched on top of a cow on the side of a California highway is still with me.

Another honorable mention is BBC's Digital Planet, which is just technology news (and not particularly technical) but Gareth Mitchell is fun and easy on the ears.
