Belkin used the added limelight of the Intel Developer Forum to show off a prototype of a Thunderbolt dock intended primarily for Mac owners. Just called the Thunderbolt Express Dock, it has much of the same expansion of Apple's Thunderbolt Display without the requisite screen. A single cable feeds out gigabit Ethernet, FireWire 800, three USB ports, and another Thunderbolt port for adding more devices to a chain.
