In the presentation Steve showed off the option to sync the {x} most recent unwatched episodes of a TV show to an iPod, is that flexibility also available for syncing Podcasts?
I actually asked for that feature a year ago, so it will be nice to see if it has actually been implemented.
(Actually thinking about it more you could probably do it by creating a smart playlist for each podcast, matching on album name, filtering to a playcount of 0, ordering by date added and limiting to one item, and then making another smart playlist that aggregates all the items in each of the individual podcast playlists for syncing to the ipod, but thats rather a lot of configuration to set up for a fairly simple requirement.)
At the moment I only have access to a Shuffle which doesn't have the option of syncing podcasts at all..
My Nano went missing some time ago, at the moment I'm using my Rio Karma in my car. I still have a Nano dock, radio remote, and about 1000 iTunes tracks, so I'm rather pointed in that direction when looking for a replacement, but the Zune is tempting too.
