Kox1 - I would love to be able to go back to having the iTunes or Music app manage podcasts (iOS 6), but from what I've found, Apple may have blocked that. When I deleted the Apple Podcasts app, and then tried opening iTunes to get/listen to a podcast, I got a message telling me that I had to download the Podcasts app to download podcasts. No go.
Podcasts currently takes a lonnnnnnngggg time to even access any podcasts in the Store (I'm guessing it was still trying to access the iTunes Store - after about a solid minute or more of "Loading...", I got fed up and quit Podcasts).
Personally, I certainly hope Apple's app team for Podcast is working on *many* improvements to Podcasts app (speed, stability, etc....). Of course, I know that Apple does not divulge any future/pending updates/upgrades.
Meanwhile, I am no longer listening to podcasts on my iPad or my iPod Touch.
Of course, that does allow me more space on either for other apps, music, documents, and such.
