Also consider your use case re: the control method you're using. If you're ever going to want to use the Deck itself as your controller, then you want a hub like this, for example and a $10 holding stand for when you have to put it down... not a dock. If you have a separate controller or are only intending to M&K while docked, then a dock is probably the best solution.
No, I velcroed it to the back of my Deck (careful not to cover any vents). You could also use an extension cord for the Deck plug in part if that's more convenient.
