It's a dual SATA hardrive dock with multi card reader and 2 usb ports and it's own power supply. It looks to have the room to adapt the front bay to hold a Nexus device with a 'pogo pin' charger hookup making it a true all in one docking station. It looks to me like it's basically a standard USB 2.0 hub with a SATA to USB converter in one of the four inputs, a multicard to USB reader in another and the remaining two brought out to the front panel. Since the Nexus 7 (and 10) works with most of these devices already this looks to me like it should work and replace the rat's nest of a powered USB hub, SATA to USB hardrive,case with cord, and a USB card reader and whatever else I plug into the powered hub.
