You can do everything on the dock that you can do with the Zune off the dock. I like the Home kit so much, I bought one for the living room, garage, and one I carry with me for work. Well, I bout 2 full kits, and I pieced together a dock, sync cable-a/c adapter and remote for work.
I get better radio reception with my Zune hooked up through the tape adapter on my boombox than through the boombox itself.
