If you are preparing to make the shift to the Zune HD or just upgrade your existing Zune, then you may want to further prepare yourself with the dock.  There are two different Zune HD add-ons now up for pre-order.  The first is a dock which connects your Zune to a TV so you can watch your 720P HD videos as well as charge your Zune HD.  The other is simply a plug for charging along with AV cables to watch your video on your TV without the convenience of the dock.  They are both available for pre-order now.

 

[Zune HD AV & Power Pack] $49.99

[Zune HD AV Dock] $89.99
