The podcast support is definitely better than iTunes. That said, one of my main gripes is what Jamlo posted which is, there needs to be an option to sync the last 'n' episodes. And not a slider, if possible, just a text box where I can say how many. For some podcasts, especially some video podcasts, I'll end up adding a bunch to my collection. That leaves me with the options to either:
Sync all unplayed and partially played: Which will usually be one or none.
Sync all downloaded: This can end up being dozens of them, taking up a lot of room.
Sync only the first unplayed: This will either be one or none.
or Don't Sync any episodes.
I'd like to be able to keep as many episodes as I like, but only sync the five latest episodes.
Mark as Played/Unplayed also desperately needs to be brought back to the Zune HD! :)
