Until WiGig docks take off next year the only thing Ultrabook users can use are the USB3.0 docks that are available from Toshiba, Lenovo and others. The problem with those is that they were designed for bigger laptops and assume you’ve already got a DVD drive. The ASUS VariDrive solves that problem.
Gigabit Ethernet, Dual display outputs, USB3.0 hub and DVD drive in one. The only thing that is missing is an analogue audio in and out port for those Skype headphones.
