Thank God! The new Zune separates podcasts from music. Not that I don't love listening to Carl Franklin or Scott Hanselman talk for hours on end, but when I play my entire music collection on shuffle mode, I don't really want to hear a talk show.
Since I kept scores of DNRs and Hanselminutes on my Zune, I found myself needing to skip tracks all of the time before now... That manual interaction proved to be quite the distraction when all I was trying to do is concentrate on a programming task.
