Seen above is a mockup of the Henge Dock system for the 17-inch MacBook. The 17-inch model dwarfs the 13-inch unit. The reason we're calling this a mock-up and not a prototype is because this particular prototype doesn't carry several of the new features we are implementing on the new units. The actual production unit will be slightly taller and will have the set screws flipped to the other side. But progress nonetheless!
