If you are a user of the 24inch or 27inch Apple Cinema Display which does not have thunderbolt ports on the back, there is still NO option for you to use your monitor AND at the same time, connect a thunderbolt peripheral device that does not have the port duplicated. These displays use the mini display port connector which will use one port on the hub, the other port will connect the hub to your MacBook Pro/Air.
Think about adding a video encoding/recording device from matrox or blackmagic design and you are stuck! Yes even the latest www.belkin.com/us/p/P-F4U055 Thunderbolt Express Dock from Belkin has only TWO ports at the back. Do not be misled by the pictures. That dark receptacle at the front is a groove that cuts through to the back allowing a tidy way to connect the cable to your MacBook Air/Pro.
I am waiting (not sure how long I can wait) for a 3 or 4 port thunderbolt hub!
