Podcasts: Brain Chow

I've owned several Bluetooth devices, but I've either lost them or found the larger of them unusable.  I came on a Plantronics model that isn't expensive and performs fairly well.  Mated with my incredibly awful Prism II T-Mobile phone and the excellent Pocketcasts application I gained access to a large set of interesting, entertaining, and informative podcasts.   There's so much good brain food audio available I find it hard to keep up with the available subscriptions.

Podcasts provide the "smart" in smartphone.
