I'm a happy man today.
I love my podcasts, I think they're better than music. But I hate iTunes on my pc. And to properly manage them on my iPad and iPhone in the past I really needed to sync the phone with iTunes.
I know I could have used stitcher or instacast, but I tried them and they just didn't cut it. The new podcast app is one step closer to not needing a pc (for some people). From the app you can browse podcasts (as you could in the iTunes app anyway) but more importantly you can subscribe and better manage your podcasts, like whether you want to delete them automatically if you have listened to them, and automatically download new ones when they come out.
Thanks John Gruber at DaringFireball for letting me know this existed.
