Even though shipping Macs have sported USB 3.0 ports for more than half a year, compatible USB 3.0 hubs have been thin on the ground. Expanding those 4.8 Gbps ports would make better use of all that bandwidth, and the increased bus power (900mA vs. 500mA for the older USB 2.0 standard) is perfect for juicing multiple devices.
