Whether it is realizing it or not, Kanex is using a pretty old marketing trick: launching a fairly common device alongside an unusual one, thus earning it attention by association.
Had the company launched the 4-Port USB 3 Hub as a standalone product, it might have even been overlooked.
The USB 3.0 Gigabit Adapter is just unusual enough to turn a few heads.
Essentially, it accepts a Gigabit Ethernet cable and lets the Internet connection be made through a USB port instead.
This is useful for consumer electronics that have Wi-Fi and USB but cannot afford to include Ethernet plug because they would have to be too thick (that makes the tablet market one potential beneficiary).
Kanex' website holds more information (usb3hub4x and usb3lan). For those who are already convinced that they want the products, the 4-Port USB 3 Hub sells for $59 (45-59 Euro) and the USB 3.0 Gigabit Adapter for $49 (38-49 Euro).
