New iOS App From Apple: Podcasts:

good for playback (including syncing your location in an episode between devices), good for discovery, good for automatically downloading new episodes

(Via Daring Fireball)

I’ve only had an initial look. From what I can see these are great features but, I can’t see how to add a podcast manually (need my CastRoller feeds) or import subscriptions. My guess is I can do this by syncing but that is most defiantly not post PC!
