Macally has recently rolled out two new USB 3.0 hubs to add functionality to your computers. Specifically designed for Apple laptops (sheerly in color and looks with the anodized aluminum housing), these two will actually work on any desktop and notebook computer with available USB 3.0 or 2.0 port. One gives you four additional USB ports while the other adds 3 USB 3.0 ports and a Gigabit Ethernet port to your computer.
They may be a little bulky for traveling with but for the new Retina display MacBook Pros that don't have an ethernet connection, the Hub with the gigabit ethernet port is a nice companion to your laptop. And with USB speeds up to 5 Gb/s, using 3.0, not to shabby either.
