An interesting idea and one of the better dock solutions, but I still dislike any dock that makes you connect all the Macbook ports - where you have to "align" the thing carefully or you'll scratch things up.
I much prefer Thunderbolt and the single connection idea. Unfortunately, there are zero Thunderbolt docks available. Belkin's standalone dock is still months away and Apple's Thunderbolt monitor is too expensive for anyone looking for just for a dock.
