I was listening to the DL.tv podcast on my Zune in my car on my way back from work today and got to the final 5 mins of the episode.  I unplugged my Zune (which automatically paused the device), got to my desktop and plugged it into my PC.  The Zune software automatically opened and started to sync. 

I wanted to listen to those last 5 minutes I had left, so I selected the episode within the Zune software and hit play.  Amazingly, the podcast resumed exactly where I left off in my car!

Not sure why I was surprised by this, or if any other portable music player does this, but I definitely was impressed!  Nice fit and finish feature that made the whole experience seem really polished.  Kudos to the Zune team.
