I listen to podcast via nexus7.
I am using podcast addict.
Main reason is that iOS podcast app playback sucks.
In that way, podcast addict is flexible in setting playback speed.
Design or something is not so good, but I don’t care about that.
In addition, 7 inch tablet is suitable for podcast, because it is easy to follow shownote links, and read the webpages. And I can also put it in my pocket.
Inspired by this post.
