A proper PowerBook Duo of modern day would be a 32" iMac-like monstrosity with a big ass slot (opening on the right) into which you slide the whole MacBook Pro, and a whole lot of ports in the back. The MBP attaches by its thunderbolt ports and magsafe in the back of the slot.
Obviously, if you have macbooks of different sizes, you would need to buy separate duos for each size. MacBook Air might have a 27" dock, incompatible with the rest.
