Kanex’s DualRole is an Ethernet hub that comes equipped with three USB 3.0 ports, a useful accessory for newer MacBooks which require an adapter to connect to a wired network.

The DualRole is USB bus powered with an included 3-inch cable, but it also supports an additional 5V power adapter (not included) to provide extra power for intensive tasks like charging the iPad and the iPhone or powering hard drives.
While DualRole supports plug and play for its USB 3.0 ports, it does require drivers to access the Gigabit Ethernet port.
Kanex’s DualRole is available immediately for $69 from the Kanex website.

And then watch it quintuple in price...
Compared to the proposed (yet seemingly non-existent) Thunderbolt hubs, it's darn cheap. Figure in the cost of an Apple Ethernet adapter for a Macbook Pro Retina and I don't think it's really that bad if you have a need for both more USB 3.0 ports and an Ethernet port (like many Macbook Pro Retina users do). Sadly, you only gain 2 ports here and that's a real problem. I simply don't get why hub makers (and even Apple on their notebooks even) offer so few ports. One external mouse and keyboard (wired) and you're DONE on a MBP Retina. It's ridiculous. My 2008 MBP has SO many more ports in total AND an upgrade slot to boot. The Retina model wastes space on the side where more ports could be added with a better design. Personally, under those conditions I'd rather have just a Mini-Display Port instead of Thunderbolt and have 4-6 USB 3.0 ports instead (utilizing all that internal space that the TB chip takes up if needed to create space near the edges of the motherboard for more ports).
What I need (for my Mac Mini which has 4-ports already) is a reliable 7-port USB3 hub and thus far the best reports for compatibility I've been able to find are 4-port hubs which would only give me 3 extra ports in total. I've already got a 7-port USB 2.0 hub MAXED OUT here (which uses one USB 3.0 port to connect) and I only have one USB 3.0 port still open as a result for any USB drives, etc. and have two more USB 3.0 3TB backup drives to connect during backups. So one more permanent type device and I have no more ports without unplugging something.
My Mac Mini doesn't need a second Gigabit port so this product doesn't interest me regardless of the number of USB 3.0 ports (i.e. no point paying for something you're not going to use unless it's the only product available), but I can see why a MBP Retina user would be interested.
